Transcript:

Eosinophilic gastritis (EoG) is a rare immune disease that occurs when white blood cells called eosinophils build up in the digestive tract in association with injury and inflammation. For individuals with EoG, this makes eating difficult or even impossible. Heartburn, nausea, vomiting, weight loss, and bloating can be painful and lifelong. However, there are currently no FDA-approved medications for EoG.

In this study, researchers investigated the use of dupilumab to improve outcomes for individuals with EoG. Forty-one participants with EoG were given dupilumab or a placebo for 12 weeks. Then, researchers evaluated outcomes, including eosinophil counts in the stomach.

Results showed that dupilumab improved the primary outcome and several secondary outcomes, including gastric eosinophil counts, histopathologic and endoscopic abnormalities, and transcriptomic biomarkers compared to the placebo group. Authors note that these findings provide a framework for larger-scale studies and improve understanding of the mechanisms of inflammation in EoG.

Transcript:

Hereditary spastic paraplegia type 4 (SPG4) is the most common form of hereditary spastic paraplegia, a large group of inherited disorders that affect the long nerve pathways carrying movement signals from the brain down the spinal cord to the legs. SPG4 is caused by changes in the SPAST gene. People with SPG4 commonly experience difficulty walking due to muscle weakness and spasticity (muscle rigidity) in the legs, as well as hyperreflexia (overactive bodily reflexes), urinary urgency or bladder dysfunction, and mild loss of vibration sense in the feet. Symptoms and time of disease onset can be very different from person to person, even within the same family. Not much is known about the natural history of SPG4, making it difficult to conduct clinical trials and find new therapies.

In this study, researchers investigated genotype–phenotype correlations and the natural history of early-onset SPG4. The team used deep phenotyping to analyze 206 patients with genetically confirmed SPG4 from seven international centers. Researchers also studied data from an additional 146 patients from previous studies.

Results provide the most detailed natural history of SPG4 to date, creating a framework that links specific genetic variants to different clinical trajectories. Authors note that these findings can improve care and optimize clinical trial design for SPG4.

Developing a New Process to Improve Diagnostic Accuracy in Leukodystrophies.

This summary is based on a paper published in the Orphanet Journal of Rare Diseases on April 28, 2026.

Leukodystrophies are a complex, often progressive group of disorders affecting the white matter of the brain due to the loss or absence of myelin, the protective coating around nerves. Different leukodystrophies can have many different genetic variants and symptoms, making them difficult to diagnose.

In this study, researchers developed a new process to improve diagnostic accuracy in leukodystrophies. First, genetic counselors with expertise in leukodystrophies review participants’ medical records, assessing the clinical, biochemical, and molecular features. Next, the team assigns diagnostic categories based on the record review. Finally, leukodystrophy physician experts consult for cases that need additional characterization or clarification.

The process has resulted in a large database of individuals with verified leukodystrophy diagnoses, improving identification of patients that can participate in natural history studies and treatment trials. Authors note that this process can also be used by other rare disease groups.

Measuring Function in Children with Leukodystrophy.

This summary is based on a paper published in the journal Developmental Medicine & Child Neurology on April 30, 2026.

Leukodystrophies are a complex, often progressive group of disorders affecting the white matter of the brain due to the loss or absence of myelin, the protective coating around nerves. Although all leukodystrophies affect neurological function, the severity and speed of progression can be very different among different types.

In this study, researchers evaluated a tool to measure function in children with leukodystrophy. Ninety-nine caregivers completed four domains (daily activities, mobility, social/cognitive, and responsibility) of a parent-reported assessment called the Pediatric Evaluation of Disability Index-Computer Adapted Test (PEDI-CAT). Researchers compared the results of the daily activities and mobility domains with clinician-administered assessments, including grasp and visual motor integrations subtests, of the Peabody Developmental Motor Scale (PDMS-2) and the 88-item Gross Motor Function Measure (GMFM-88).

Results showed a strong agreement between the PEDI-CAT and the above standard assessments. This suggests that the PEDI-CAT is a reliable way to measure functional abilities in leukodystrophy, especially when clinician-administered assessments are not possible. The authors note that the PEDI-CAT is a potentially critical tool for leukodystrophy families to be able to participate in research remotely.

Developing a New Patient-Centered Approach to Clinical Trial Readiness in Aicardi-Goutières Syndrome.

This summary is based on a paper published in the journal Molecular Genetics and Metabolism in March 2026.

Aicardi-Goutières syndrome (AGS) is a type 1 interferonopathy primarily associated with multisystemic involvement, including severe neurologic impairment. With advancements in therapeutics for disorders such as AGS, there is an urgent need to ensure that patient voices are included early in the design of clinical trials.

In this study, researchers developed a new patient-centered approach to clinical trial readiness and piloted the approach in AGS. First, the team worked with patients and caregivers to identify their health priorities for improvement. Following this, the team engaged a panel of disease experts to identify the priorities applicable in the context of AGS clinical trials (Concepts of Interest). Next, through consensus building among a panel of outcome experts, the team selected Clinical Outcome Assessments able to measure the identified Concepts of Interest. Finally, the team presented the Concepts of Interest and the aligned Clinical Outcome Assessments to patients and caregivers to establish the feasibility of completion of these assessments in clinical trials.

This process led to the identification of a panel of fit-for-purpose Concepts of Interest and Clinical Outcome Assessments pairs that can be used to identify endpoints for future AGS clinical trials and natural history studies. Authors note that this approach can be applied to other leukodystrophies and rare diseases.

Characterizing Movement Disorders and Treatment Responses in Aicardi-Goutières Syndrome.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology on April 25, 2026.

Aicardi-Goutières syndrome (AGS) is a genetic autoinflammatory disorder primarily affecting the brain, skin, and immune system. Individuals with AGS can experience a wide range of neurological symptoms, even when they have the same gene mutation, causing many to be misdiagnosed as having cerebral palsy.

In this study, researchers characterized movement disorders and treatment responses in AGS. The team evaluated motor symptoms, neuroimaging, and interferon signatures in seven children with AGS treated with immunomodulatory therapies.

Results show that these therapies were associated with reduced systemic inflammation and stabilized disease. However, only some participants experienced improved motor function, suggesting that established central nervous system injury may limit recovery. Authors note that these findings highlight the need for early recognition and treatment before further injury may occur.

Investigating Self-Reported Health-Related Quality of Life in Adults with Urea Cycle Disorders.

This summary is based on a paper published in the Journal of Inherited Metabolic Disease on April 9, 2026.

Urea cycle disorders (UCDs) are a group of inherited, metabolic disorders characterized by hyperammonemia (high blood ammonia levels). People diagnosed with a UCD often require ongoing health surveillance, long-term treatments, and emergency management for hyperammonemic episodes. Although many studies have focused on health-related quality of life in children with UCDs, fewer have focused on adults.

In this study, researchers investigated self-reported health-related quality of life in adults with UCDs. The team assessed patient-reported outcome measures in 144 adults with UCD.

Results reveal that adults with UCDs report similar health-related quality of life as adults in the general population. Despite significant differences in measured cognitive ability, symptomatic and asymptomatic individuals reported similar behavioral health and daily functioning scores. Authors note that more studies are needed to better understand and measure health-related quality of life in people with UCDs.

Advancing Treatment in Congenital Thrombotic Thrombocytopenic Purpura.

This summary is based on a paper published in the journal Research and Practice in Thrombosis and Haemostasis on January 20, 2026.

Congenital thrombotic thrombocytopenic purpura (cTTP) is a disorder in which blood clots form in the small blood vessels throughout the body. cTTP is caused by mutations in the ADAMTS-13 gene, leading to microvascular thrombosis (abnormal clotting), hemolytic anemia (destruction of red blood cells), and organ damage.

In this review, researchers summarize the clinical course, complications, and advances in treatment of cTTP. The team reviewed registry data, clinical studies, expert guidelines, and real-world patient experiences, including pregnancy management.

Results suggest that recombinant ADAMTS-13, a therapy that helps restore the ADAMTS13 enzyme, is more effective, safe, and convenient than the standard plasma therapy. Authors note that although recombinant ADAMTS-13 represents a major advance in cTTP management, more studies are needed to evaluate its long-term safety, particularly during pregnancy, and to optimize treatment strategies.

Investigating the Impact of Demographic Trends on Disease Prognosis in Myasthenia Gravis.

This summary is based on a paper published in the Journal of Neurology on March 23, 2026.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which compromises nerve muscle communication, causing disabling weakness. In the past 50 years, the epidemiology of MG—how often it occurs in different groups of people and why—has changed over time. However, not much is known about how these changes have impacted management of MG.

In this study, researchers investigated how demographic trends have affected disease prognosis in MG. The team assessed demographics, MG subtypes, and antibody status over 50 years in 1,023 patients with AChR-MG. In 517 patients, the team also evaluated treatment response and adverse events over 20 years.

Results show an increased rate of patients diagnosed with very late-onset MG. Authors note that patients with very late-onset MG may face an increased risk of long-term treatment exposure and adverse events, especially in elderly patients.

Creating a Patient Registry to Improve Health Outcomes for Individuals with Sex Chromosome Aneuploidies.

This summary is based on a paper published in the American Journal of Medical Genetics in January 2026.

Sex chromosome aneuploidies (SCAs) are a group of conditions in which an individual has either extra or missing X and/or Y chromosomes present in the cells of their body. Although SCAs are the most common chromosomal abnormality, they are often underdiagnosed. Research in SCAs has been limited by over-representation of more severely impacted individuals in clinical studies, as well as low geographic and demographic diversity.

In this study, researchers partnered with the SCA community to create a patient registry to improve health outcomes for individuals with SCAs. The Generating Advancements with Longitudinal Analysis in X and Y variations (GALAXY) Registry helps advance SCA research by collecting, storing, and analyzing clinical data from SCA patients.

To date, GALAXY includes hundreds of participants with a verified diagnosis of SCA. Next, researchers plan to recruit more individuals from underrepresented groups, extract medical record data into the registry, expand internationally, and continue to engage with the SCA community. Authors note that the GALAXY Registry is a powerful resource for future patient-centered clinical research.

Characterizing the Spectrum of ATP1A3-Related Disorders.

This summary is based on a paper published in the journal Movement Disorders on March 18, 2026.

ATP1A3-related disorders are a group of neurological conditions caused by mutations in the ATP1A3 gene. Due to the broad spectrum of clinical features and disease-causing variants, it can be challenging to classify these disorders.

In this study, researchers characterized the spectrum of ATP1A3-related disorders. The team evaluated 88 individuals with pathogenic or likely pathogenic variants in ATP1A3. Researchers used these observations to explore symptoms and genotype–phenotype relationships, as well as build a video archive.

Results reveal that most individuals with ATP1A3-related disorders show overlapping or atypical features, including presentations with progressive spastic paraparesis, which is typical of hereditary spastic paraplegia. Authors note that these findings support a shift toward flexible clinical approaches based on symptoms rather than relying on rigid classifications.

Exploring the Impact of Ornithine Transcarbamylase Gene Variants in Asymptomatic Individuals.

This summary is based on a paper published in the journal HGG Advances on January 15, 2026.

Ornithine transcarbamylase deficiency (OTCD) is a type of urea cycle disorder characterized by hyperammonemia (high blood ammonia levels) due to deficiency or absence of an enzyme needed to convert nitrogen from protein into urea (a waste product). As genetic testing becomes more widely utilized in a variety of clinical contexts, an increasing number of asymptomatic individuals with variants in the OTC gene are being identified incidentally. However, there is a lack of guidance for counseling and management of these individuals.

In this study, researchers explored the impact of OTC variants in asymptomatic individuals. The team reviewed medical records, the Urea Cycle Disorders Consortium database, and published reports to characterize two common OTC gene variants. Researchers also tested the variants in a lab yeast model to measure enzyme activity.

Results revealed a risk of late-onset hyperammonemia for males with the two common OTC gene variants. Common triggers included fasting, illness, and high-protein diets. Authors note that these findings can help guide counseling of individuals with these variants, including the importance of knowing the signs and symptoms of hyperammonemia as well as potential triggering factors.

Investigating Language Skills in Children with Alexander Disease.

This summary is based on a paper published in the American Journal of Speech-Language Pathology on January 13, 2026.

Alexander disease is a rare disorder of the nervous system characterized as a leukodystrophy, a group of disorders affecting the myelin (the fatty coating surrounding nerve fibers). People with Alexander disease may have trouble walking, speaking, and swallowing.

In this study, researchers investigated the relationship between disease characteristics, age, and language skills in patients with Alexander disease. First, the team used clinical and imaging features to determine disease subtypes—including cerebral, intermediate, and bulbospinal—among 82 participants. Next, they used developmentally appropriate tests to assess participants' language and functional communication abilities. Then, they used statistical methods to find differences across groups.

Results showed that overall, cerebral patients experienced the most significant language deficits compared to intermediate and bulbospinal patients. Authors note that these findings can be used to better understand the impact of communication deficits and to provide accommodations and interventions in treatment plans for patients with Alexander disease.

Evaluating the Use of Genome Sequencing in Diagnosing Children with Progressive Movement Disorders.

This summary is based on a paper published in the journal Brain on February 5, 2026.

Childhood-onset movement disorders have a large range of symptoms and genetic causes. Over 500 different genes are associated with these disorders. However, standard genetic testing may not detect some of the genetic variants.

In this study, researchers evaluated the use of genome sequencing in diagnosing children with progressive movement disorders. First, the team used whole genome sequencing to identify variants in 100 children and young adults with early-onset progressive movement disorders and prior nondiagnostic testing. Then, a multidisciplinary team interpreted the variants and matched them with different phenotypes.

Results included a molecular diagnosis in 27% of cases, with candidate variants identified in an additional 33%. Short-read whole genome sequencing showed a small increase in diagnoses over exome sequencing. Most of the diagnoses were achieved through reanalysis of exome-level data. Authors note that these findings highlight the importance of repeat variant interpretation and the need for improved analytic pipelines to fully realize the potential of genome sequencing.

Exploring the Use of Glial Fibrillary Acidic Protein as a Biomarker in Alexander Disease.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology on January 9, 2026.

Alexander disease is a rare disorder of the nervous system characterized by leukodystrophy, or the destruction of myelin (the fatty coating surrounding nerve fibers). In patients with Alexander disease, variants in the GFAP gene lead to the buildup of glial fibrillary acidic protein (GFAP) in the body. Not much is known about the relationship between GFAP levels and disease characteristics.

In this study, researchers explored the use of GFAP as a biomarker in Alexander disease. First, the team collected cerebrospinal fluid and plasma from participants with and without Alexander disease. Next, they compared the concentration of GFAP over time between these groups, including those with common disease characteristics or genetic variants.

Results showed that GFAP increases over time in young children with Alexander disease. The highest concentrations of GFAP were seen in those with the cerebral disease type. Authors note that these findings are a critical initial step in defining biomarker validation and context of use for GFAP in Alexander disease.

Reviewing Pathology and Interventions in Cerebral X-Linked Adrenoleukodystrophy.

This summary is based on a paper published in the Journal of Child Neurology in February 2026.

X-linked adrenoleukodystrophy (ALD) is a disorder on the X chromosome characterized by the disruption in fat metabolism (break down) which leads to the accumulation of long-chain fatty acids throughout the nervous system, adrenal glands, and testes. More than half of male patients with ALD develop progressive, inflammatory cerebral demyelination (loss of the fatty coating surrounding nerves). Treatment for cerebral ALD is limited, with no standard therapies available for the advanced form.

In this study, researchers reviewed pathology and interventions in cerebral X-linked ALD. The review included over 50 years of published literature and expert opinion from clinicians caring for patients around the world. From these sources, the team gathered information on immunopathology, biomarkers, and therapies tested.

Findings revealed insights on inflammation and immunomodulation in cerebral X-linked ALD. Authors note that these findings highlight the potential of a future clinical trial of immunomodulatory agents for advanced cerebral ALD.

Using a New Statistical Technique for Accelerometer Data to Assess a Treatment for Mitochondrial Disease.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology in December 2025.

Mitochondrial diseases are multisystemic, genetic disorders involving dysfunction of the mitochondria (specialized cell structures that produce energy), which affects cellular metabolism. Development of new therapies for mitochondrial diseases is difficult due to a lack of outcome measures.

In this study, researchers used a new statistical technique for accelerometer data to assess a treatment for mitochondrial disease. First, the team collected data over several clinic visits from 14 patients with thymidine kinase 2 deficiency (TK2d), an ultra-rare autosomal recessive mitochondrial disease, in a clinical trial for nucleoside therapy. Next, the team used a combination of functional data analysis and longitudinal mixed-effects linear regression to compare accelerometer data over the course of treatment.

Results showed that nucleoside therapy resulted in significant improvement in activity levels among TK2d patients. Authors note that these findings could reveal a possible primary outcome biomarker in clinical trials for mitochondrial diseases as well as other types of diseases, both rare and common.

Assessing Health-Related Quality of Life in Children with Rare Forms of Hereditary Spastic Paraplegia.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology on November 6, 2025.

Hereditary spastic paraplegia (HSP) is a large group of inherited disorders that affect nerves that send messages to the muscles. Patients with HSP commonly have difficulty walking due to muscle weakness and spasticity (muscle rigidity) in the legs. In patients with rare forms of HSP, these symptoms can be more complex, including developmental delay, intellectual disability, movement disorders, dysphagia (difficulty swallowing), or incontinence. While previous studies have examined how common forms of HSP affect health-related quality of life, less is known about the impact of rare childhood-onset forms.

In this study, researchers assessed health-related quality of life in 80 children with rare forms of HSP. Using the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) and clinician-reported outcomes, the team examined how clinical features, age, and genotype correlate with quality of life.

Results showed that CPCHILD can be used to assess many different forms of childhood-onset HSP. Lower scores were seen in children with more complex forms. Motor, autonomic, and bulbar symptoms had the largest impact. Authors note that these insights can help clinicians prioritize interventions and inform strategies to improve quality of life for children with HSP.

Investigating the ATG9A Ratio as a Diagnostic Tool for Adaptor Protein Complex 4–Associated Hereditary Spastic Paraplegia.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology on January 5, 2026.

Hereditary spastic paraplegia (HSP) is a group of inherited neurological disorders that cause the upper motor neurons to slowly degenerate, leading to progressive muscle stiffness and leg weakness. Adaptor protein complex 4–associated HSP (AP-4-HSP) is a childhood-onset and complex form of HSP that causes mislocalization—buildup in the wrong location—of the protein ATG9A. Gradual progression of initial symptoms, similarity with other developmental conditions like cerebral palsy, and unknown significance of genetic variants can make it challenging to diagnose AP-4-HSP.

In this study, researchers investigated the ATG9A ratio as a diagnostic tool for AP-4-HSP. The team measured the mislocalization of ATG9A in eight patients with suspected AP-4-HSP and genetic variants of unknown significance.

Results demonstrated loss of AP-4 function in six of the participants, revealing new disease-causing genetic variants. Authors note that the ATG9A ratio is a useful tool for diagnosing AP-4-HSP and classifying new genetic variants, which can help determine eligibility for clinical trials and guide treatment decisions.

Evaluating a New Food Photography App for Measuring Dietary Intake in Urea Cycle Disorders.

This summary is based on a paper published in the journal Molecular Genetics and Metabolism in December 2025.

Urea cycle disorders (UCDs) are a group of inherited, metabolic disorders characterized by hyperammonemia (high blood ammonia levels). Nutrition management can help prevent hyperammonemia by limiting protein intake while providing enough energy for growth. However, traditional methods of assessing dietary intake—including three-day diet records, 24-hour recalls, and food frequency questionnaires—are often time-consuming and inaccurate.

In this study, researchers evaluated a new food photography app for measuring dietary intake in individuals with UCDs. Eight participants used the new app, mFood, to take photos of meals and snacks for remote analysis by a registered dietician. The team then compared the accuracy of mFood with traditional three-day diet records.

Results revealed few statistical differences between mFood and traditional methods. However, the majority of participants preferred using mFood, offering a more convenient way for individuals with UCDs to collect nutrition information.

Assessing Temporomandibular Joints in Patients with Osteogenesis Imperfecta.

This summary is based on a paper published in the journal Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology on September 16, 2025.

Osteogenesis imperfecta (OI) is a group of inherited connective tissue disorders associated with a wide range of symptoms, including fragile bones that break easily. Individuals with OI can experience problems with bone formation and function.

In this study, researchers assessed temporomandibular joints—which connect the jawbone to the skull—in patients with OI. First, the team used cone-beam computed tomography (CBCT) to create 3D images of the temporomandibular joints of 48 OI patients and 48 age- and sex-matched controls. Next, they evaluated mandibular condylar volume and height.

Results showed that individuals with OI had significantly reduced condylar volume and height. Authors note that these findings indicate impaired and delayed condylar development consistent with overall skeletal maturation delay in OI.

Evaluating Plasma Neurofilament Light Chain as a Biomarker for Hereditary Spastic Paraplegia-SPG11 and -ZFYVE26.

This summary is based on a paper published in the journal Movement Disorders on December 9, 2025.

Hereditary spastic paraplegia (HSP) is a large group of inherited disorders that affect nerves that send messages to the muscles. HSP-SPG11 and HSP-ZFYVE26 are autosomal-recessive forms of HSP, meaning that they are caused by two mutated copies of a gene. More information is needed about measurable signs of these disorders for new therapeutic trials.

In this study, researchers evaluated plasma neurofilament light chain (pNfL) as a biomarker for HSP-SPG11 and HSP-ZFYVE26. The team analyzed pNfL levels in 57 patients with HSP, collecting clinical and biomarker data over five years.

Results showed significantly elevated baseline pNfL levels in patients with HSP, reflecting early neuroaxonal injury. However, authors note that baseline pNfL did not help predict future disease progression.

Exploring the Spectrum of Movement Disorders in Early-Onset Hereditary Spastic Paraplegia.

This summary is based on a paper published in the journal Movement Disorders on December 2, 2025.

Hereditary spastic paraplegia (HSP) is a large group of inherited disorders that affect nerves that send messages to the muscles. Individuals with early-onset HSP can experience movement disorders, but not much is known about why and how often they occur.

In this study, researchers explored the spectrum of movement disorders in early-onset HSP. The team analyzed data from 428 children and young adults with HSP, reviewing clinical characteristics and video examinations.

Results showed that movement disorders—including dystonia, parkinsonism, and ataxia—were common in childhood-onset HSP. Authors note that routine screening and management tailored to specific genotypes of movement disorders—especially dystonia—may improve functional outcomes and quality of life.

Transcript:

Eosinophilic gastrointestinal disorders (EGIDs) are a group of chronic immune system disorders in which a type of white blood cell (eosinophils) build up in the gastrointestinal tract, causing inflammation or injury. Some types of EGIDs—particularly non-eosinophilic esophagitis (EoE)—are not well characterized, with management relying on expert opinion.

In this article, researchers from CEGIR—including the principial investigator and two scholars—collaborate to explore the use of artificial intelligence (AI) tools in the detection and management of EGIDs. The team outlines present and future AI applications, including prediction of disease trajectories, personalization of treatment, clinical decision support, patient education, and clinical monitoring.

Authors note that although AI holds potential to enhance EGID diagnosis and management, realizing this promise will require nuanced, multifaceted evaluation of its ability to positively transform research and clinical practice.

Transcript:

Neurodevelopmental genetic disorders (NGDs) are a spectrum of conditions that affect how the brain functions. Individuals with NGDs often experience sleep problems, which also affects their ability to function during the daytime. Despite these common issues, not much is known about predictors of sleep problems in NGDs.

In this study, researchers characterized key factors that correlate with sleep problems in rare NGDs. Parents of 173 individuals with rare NGDs—including PTEN hamartoma tumor syndrome, SYNGAP1, NFIX, and a mixed group of other NGDs—completed the Neurobehavioral Evaluation Tool. The team used these evaluations to characterize sleep phenotypes across disorders and examine predictors of poor sleep.

Results highlighted the elevated severity of sleep problems in NGDs, particularly in those with SYNGAP1. Predictors for each sleep problem varied, suggesting that accurate assessment and diagnosis of sleep problems—as well as evaluation of correlates of sleep difficulties—are required in order to provide targeted interventions in rare NGDs.

Transcript:

Tuberous sclerosis complex (TSC) is a genetic disorder that leads to the growth of non-cancerous tumors in multiple organs. In the brain, these include “tubers,” areas of abnormal tissue just beneath the cortical surface that can cause seizures and disrupt normal brain function. Magnetic resonance imaging (MRI) is commonly used to identify how many tubers are present, how large they are, and where they are located. These features often relate to the type and severity of a person’s neurological symptoms.

In this study, researchers created a fully automated neural network (an artificial intelligence-based program) to detect tubers on MRI and measure their total volume. They trained the model using 263 brain MRI scans from 196 individuals with TSC. They then compared the algorithm’s performance with measurements made by an expert neuroradiologist.

The algorithm’s estimates of total tuber load showed an almost perfect match with the expert standard. The authors conclude that this tool provides an objective and consistent way to identify and measure tubers, which may improve the reliability of TSC research across different sites.

Transcript:

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles, causing disabling weakness. Detailed physical examinations are required to help understand the fluctuation of symptoms, presenting unique challenges for remote assessment.

In this study, researchers review how they built a quantitative telemedicine platform for evaluation of patients with MG. The platform augments traditional neurological assessments using computer vision, signal processing, and augmented intelligence. To develop the technology, the team used video examinations of 52 patients with MG recorded twice, applying machine learning algorithms to extract clinically relevant features from video and audio data.

Results revealed that variations in examiner instructions and video quality significantly affect reliability. Authors note that a digital examination framework can enhance MG assessment precision, reduce variability in physical examination evaluation, and support the telemedicine examination.

Assessing Disparities in Access to Clinical Care and Research for Patients with Hereditary Hemorrhagic Telangiectasia.

This summary is based on a paper published in the Orphanet Journal of Rare Diseases on August 28, 2025.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited disorder of the blood vessels that can cause excessive bleeding. Patients with rare diseases like HHT are more likely to experience increased health outcome disparities due to inequitable healthcare.

In this study, researchers assessed disparities in access to clinical care and research for patients with HHT. First, the team collected race data from BVMC study recruits at HHT clinics in Toronto and San Francisco. Next, they compared the racial differences between HHT patients recruited for research and HHT patients in the general population.

Results reveal preliminary evidence of racial differences between HHT center clinic patients and surrounding populations. Findings also show an association between race and enrollment to HHT research studies. Authors note that this study lays the foundation for beginning to address disparities in HHT care and research.

Working with Caregivers to Capture Lived Experiences of Children with Multiple Sulfatase Deficiency.

This summary is based on a paper published in the Journal of Child Neurology in November 2025.

Rare diseases deeply affect children and families, but their experiences are only incompletely understood—especially for extremely rare conditions like multiple sulfatase deficiency (MSD), a leukodystrophy.

In this study, researchers worked directly with caregivers to capture lived experiences of children with MSD. Nineteen caregivers shared information about their child’s daily skills, emotional health, and overall quality of life, as well as their own well-being. The team used several established questionnaires to measure these areas and compared the results to data from metachromatic leukodystrophy (MLD), a related rare disorder.

Results showed that although children with MSD face significant challenges with daily activities, caregivers reported that emotional well-being was a strength, underscoring the incredible resiliency of the rare disease community. When the team used caregiver-centered tools, they captured a richer picture of what matters most to families, such as coordination of care and emotional support. Caregivers themselves experienced major emotional and practical strain, often feeling grief and isolation, similar to those caring for children with MLD.

Authors note that these insights show why including patient and caregiver perspectives in research is critical. Their input helps identify meaningful outcomes, improves the design of clinical trials, and ensures that future treatments focus on what truly matters to families.

Evaluating the Therapeutic Potential of Immunoglobin G- and Immunoglobin M-Specific Proteases in Acetylcholine Receptor-Positive Myasthenia Gravis.

This summary is based on a paper published in the journal Proceedings of the National Academy of Sciences of the United States of America on October 21, 2025.

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which antibodies targeting the acetylcholine receptor (AChR) cause muscle weakness. Current therapies help many patients, but some remain refractory, underscoring the need for more personalized approaches.

In this study, researchers evaluated the therapeutic potential of S-1117, a pan-IgG–specific protease engineered to selectively cleave the Fcγ region of pathogenic AChR-IgG. Using live cell-based assays with monoclonal autoantibodies and patient serum, the team showed that S-1117 effectively impaired IgG-mediated complement activation on AChR-expressing cells.

Importantly, the work uncovered a previously unrecognized MG subset driven by pathogenic AChR-IgM, which either amplified IgG-mediated injury or served as the primary source of complement activation. An IgM-specific protease fully suppressed IgM-driven pathogenicity, and combining IgG- and IgM-targeted enzymes achieved broader inhibition.

These findings reveal critical disease heterogeneity in MG and highlight Ig-specific proteases as a promising precision-medicine strategy to improve treatment for patients with antibody-mediated weakness.

Discovering a New Pathogenic Variant in Canavan Disease.

This summary is based on a paper published in the journal Human Gene Therapy on September 12, 2025.

Canavan disease is a progressive type of leukodystrophy caused by variants in the ASPA gene. In patients with Canavan disease, increased levels of N-acetylaspartic acid lead to symptoms including developmental delay, abnormal muscle tone, and macrocephaly (larger than typical head size). In order for patients to receive a complete diagnosis, all pathogenic variants in the ASPA gene must be identified.

In this study, researchers discovered a new pathogenic variant in Canavan disease. First, the team identified five patients with a clinical and biochemical diagnosis of Canavan disease, but no second pathogenic variant. Next, they used the gene editing tool CRISPR-Cas9 and long-read sequencing technique to analyze the gene structure of ASPA in these patients.

Results revealed a previously unidentified variant of the ASPA gene involving the insertion of an SVA_E retrotransposon into intron 4 of the ASPA gene. Authors note that these findings can improve genetic counseling for families and increase access to gene therapy trials.

Comparing Differences in Proteins Among Patients with Early-Onset and Late-Onset Myasthenia Gravis.

This summary is based on a paper published in the journal Annals of Neurology on September 6, 2025.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles, causing disabling weakness. Patients with early-onset MG develop symptoms before age 50, while patients with late-onset MG develop symptoms after age 50. Not much is known about how early-onset and late-onset MG affect the body differently.

Utilizing sera (the liquid part of blood that remains after coagulation) from the NIH-sponsored BeatMG clinical trial and MGNet, researchers performed proteomics analysis of 768 inflammatory proteins and uncovered a distinct immunological signature that differentiates late-onset from early-onset myasthenia gravis.

Pathways linked to leukocyte differentiation and myeloid cell migration were enriched in late-onset disease. Seven proteins were further replicated in the UK Biobank, and IL18R1, CXCL17, and CCL11 were validated in an independent cohort that were specific to late-onset MG. Investigators note that further studies are needed to confirm the use of these proteins as biomarkers of late-onset MG, as well as their use for improving therapeutic precision and patient outcomes.

Comparing Circulating microRNAs in Neurovascular Disorders.

This summary is based on a paper published in the journal Biochemistry and Biophysics Reports on August 2, 2025.

Familial cerebral cavernous malformations (FCCM), Sturge-Weber syndrome (SWS), and hereditary hemorrhagic telangiectasia (HHT) are neurovascular disorders caused by genetic mutations that can lead to brain bleeding. Cerebral microbleeds (CMBs) are another type of neurovascular disorder that causes brain bleeding. However, CMBs are more often associated with the aging process than genetic factors.

In this study, researchers compared circulating microRNAs in these four neurovascular disorders. First, the team identified differentially expressed plasma microRNAs from patients with FCCM, SWS, HHT, and CMB. Next, they used analysis techniques to identify gene targets of the differentially expressed microRNAs and their associated pathways.

Results revealed both similarities and differences in microRNAs. Among all four disorders, dysregulated microRNAs targeted the PI3K-Akt and ROBO SLIT signaling pathways. Authors note that these findings reveal shared mechanistic pathways underlying vascular dysmorphism and bleeding, highlighting their potential use for disease monitoring and therapeutic intervention.

Examining the Molecular Mechanisms of Adult-Onset Leukoencephalopathy with Axonal Spheroids and Pigmented Glia.

This summary is based on a paper published in the journal Nature Immunology on June 26, 2025.

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a neurodegenerative disorder that affects the white matter of the brain. ALSP is caused by mutations in the CSF1R gene, which provides instructions for making a protein called the colony-stimulating factor 1 receptor (CSF1R). This protein plays a crucial role in the growth and survival of immune cells in the brain called microglia.

In this study, researchers examined the molecular mechanisms of ALSP. The team performed single-nucleus RNA sequencing on brain specimens with and without ALSP.

Results revealed distinctive characteristics of ALSP brains, including significantly lower amounts of microglia and impaired maintenance of brain white matter. Authors note that these findings highlight potential therapeutic strategies for ALSP and other genetically caused microgliopathies.

Exploring the Effect of Atypical B Cells on Immune Response in Myasthenia Gravis.

This summary is based on a paper published in the journal Frontiers in Immunology on June 17, 2025.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors (AChR) in muscles, causing disabling weakness. Subtypes of MG—AChR-positive MG and muscle-specific kinase (MuSK)-positive MG—have different immune responses that may be caused by atypical B cells, an emerging subset of immune cells implicated in autoimmunity.

In this study, researchers explored the effect of atypical B cells on immune response in MG. The team used spectral flow cytometry to analyze atypical B cells in individuals with AChR-MG and MuSK-MG as well as healthy controls.

Results revealed that MG subtypes show distinct atypical B cell profiles that are linked to immunopathology and disease onset. Authors note that these findings highlight the potential for atypical B cells as therapeutic targets in both immunoglobin G1-3- and immunoglobin G4-mediated autoimmunity.

Investigating Pathogenic Properties of Acetylcholine Receptor Autoantibodies in Myasthenia Gravis.

This summary is based on a paper published in the journal Neurology Neuroimmunology & Neuroinflammation on July 18, 2025.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages the neuromuscular junction in muscles, causing disabling weakness with characteristic fluctuation in severity over time. The most common form of MG is caused by acetylcholine receptor (AChR) autoantibodies, which either block the AChR, increase their removal from the muscle surface, or block complement.

In this study, researchers investigated the pathogenic properties of AChR autoantibodies in MG and whether they varied over time in relationship to severity of disease. The team analyzed serum specimens from 50 patients with MG collected every six months for two years. Next, they used live cell-based assays to measure AChR autoantibody isotypes, immunoglobulin G subclasses, and the nature of the pathogenic mechanisms.

Results showed that the pathogenic mechanisms of the antibodies fluctuated over time and were generally not associated with disease severity. Authors concluded that additional studies of autoantibody pathogenicity should be incorporated into MG clinical trials to assess differential treatment responses.

Osteogenesis imperfecta (OI) is a group of inherited connective tissue disorders associated with a wide range of symptoms, including fragile bones that break easily. Not much is known about the psychosocial impact of OI during childhood on caregivers and families.

In this study, researchers explored caregiver experiences, existing social support provided for families affected by OI, and the impact of OI on family life. The team analyzed survey responses from 13 caregivers of individuals with OI to develop themes on the psychosocial impact of OI on the family unit.

Results revealed four themes, including encountering difficult experiences during diagnosis of OI, caregiver well-being and coping, broad family impact, and the existence and further need for social support. Authors note that these findings have implications for child and caregiver well-being and health care professionals during diagnosis, as well as emphasize the need for social support for families affected by OI.

Investigating the Correlation Between Disease Severity and Genetic Variants in Charcot-Marie-Tooth Disease Type 1E.

This summary is based on a paper published in the journal Brain on June 9, 2025. Charcot-Marie-Tooth disease type 1E (CMT1E) is a neuromuscular disorder that affects the peripheral nerves of the feet and hands, leading to neuropathy. Since CMT1E is caused by different kinds of variants in the PMP22 gene, patients can experience a spectrum of mild to severe symptoms. Not much is known about the natural history and symptom progression among these individuals.

In this study, researchers investigated the correlation between disease severity and genetic variants in CMT1E. First, the team evaluated patients with CMT1E during initial and follow-up visits at sites within the Inherited Neuropathy Consortium, documenting clinical characteristics and evaluating changes over time. Next, researchers correlated PMP22 variants with disease severity.Results revealed 24 likely disease-causing PMP22 variants among 50 individuals.

The team found that reduced expression of PMP22 at the cell surface—and the location of missense variants within the transmembrane domain—correlated with disease severity. In addition, pathogenic PMP22 variants located within the transmembrane regions were often found to cause moderate to severe disease beginning in early childhood, impairing trafficking to the plasma membrane.

Evaluating Health-Related Quality of Life and Family Function in CLN3 Disease.

This summary is based on a paper published in the journal Pediatric Neurology on June 16, 2025.

CLN3 disease, also known as Batten disease, is an inherited neurodegenerative disorder that typically starts in childhood. Because CLN3 disease is progressive and fatal, it is likely to affect the health-related quality of life (HRQOL) of both the child and the family.

In this study, researchers evaluated the HRQOL and family function in individuals with CLN3 disease and their families. The team analyzed data from 71 participants who completed assessments on the child HRQOL and family impact. In 21 of these participants, the team also analyzed Unified Batten Disease Rating Scale responses.

Results showed an association between worse child HRQOL and more severe disease symptoms, including physical impairment and functional capability. However, family impact severity was not associated with CLN3 disease symptom severities. While child HRQOL worsened over time, family impact did not significantly change over time. Authors note that these findings may provide important information for clinical care and trial design in CLN3 disease.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles, causing disabling weakness. New treatments have recently emerged for acetylcholine receptor (AChR) antibody-positive MG (AChR-MG). However, not all patients experience significant improvement, highlighting the importance of including the patient perspective in outcome evaluations.

In this study, researchers validated the Patient-Acceptable Symptom State (PASS) question as an outcome measure in AChR-MG. The team analyzed PASS responses among 173 patients with AChR-MG.

Results confirmed the PASS question as an effective, concise tool to assess AChR-MG patients' satisfaction with their disease control. Authors note that these findings also highlight the relevance of ocular complaints in patients' perception of MG burden.

Exploring the Relationship Between Genomic Diversity and Neurodevelopmental Versus Cancer Risks in Individuals with PTEN Hamartoma Tumor Syndrome.

This summary is based on a paper published in the journal npj Genomic Medicine on May 20, 2025.

PTEN hamartoma tumor syndrome (PHTS) is a spectrum of disorders caused by mutations in the PTEN gene, which typically suppresses formation of tumors. Individuals with PHTS have increased risks of cancer and neurodevelopmental disorders, including autism spectrum disorder (ASD). Not much is known about why patients with PHTS are at increased risk for these seemingly unrelated outcomes.

In this study, researchers explored the relationship between genomic diversity and neurodevelopmental versus cancer risks in individuals with PHTS. The team analyzed the genotypes of 376 individuals with PHTS and grouped them according to clinical phenotypes of neurodevelopmental disorders (including ASD) and non-neurodevelopmental disorders (including cancer).

In the neurodevelopmental disorders group, results revealed an increased accumulation of homozygous common variants in genes involved in inflammatory processes. In the ASD group, researchers also found an increased accumulation of homozygous common variants in genes involved in differentiation and chromatin structure regulation. However, in the cancer group, the team found an increased accumulation of homozygous ultra-rare variants in genes modulating cell death.

Authors note that these findings suggest a new concept of genomic diversity as a modifier of neurodevelopmental and malignant phenotypes in those with PHTS. Results also demonstrate potential clinical utility—especially for neurodevelopmental phenotypes—for better PHTS patient management.

Using Genome Sequencing to Identify Additional Molecular Diagnoses in Phelan-McDermid Syndrome.

This summary is based on a paper published in the American Journal of Medical Genetics on June 16, 2025.

Phelan-McDermid syndrome (PMS) is a genetic neurodevelopmental disorder that results from the loss of a small piece of chromosome 22 or variants in the SHANK3 gene. Symptoms of PMS include intellectual disability, autism spectrum disorder, low muscle tone, and absent speech. However, these symptoms can vary widely from person to person, even among those with the same molecular cause.

In this study, researchers used genome sequencing to identify additional molecular diagnoses that may contribute to symptom variability in PMS. The team analyzed genome sequencing and chromosomal microarray in 20 individuals with PMS.

Results revealed a second molecular finding associated with a neurological condition in three participants. Five additional new molecular diagnoses were associated with a clinically actionable secondary or incidental finding. Authors note that this study provides early evidence for the potential use of expanded sequencing among individuals with PMS, even for those without symptoms outside of the expected range.

Examining Metabolomic Changes in a Patient with PGM1-Congenital Disorder of Glycosylation and Leigh Syndrome.

This summary is based on a paper published in the journal Cells on April 25, 2025.

Inherited metabolic disorders (IMDs) are a large group of genetically inherited disorders that affect the metabolism. Although there are currently about 1,450 different types of IMDs, they are individually rare, and even more rare for one individual to have two IMDs.

In this study, researchers examined metabolism changes in a patient with pathogenic variants in the PGM1 and NDUFA13genes. The team evaluated fibroblasts from the patient, who had presented with characteristics of both PGM1-congenital disorder of glycosylation (CDG) and Leigh syndrome (mitochondrial disease) to better understand the cause of these characteristics.

Results showed a depletion of the UDP-hexose enzyme as well as impairment of complex I enzyme activity and mitochondrial function. Based on these findings, the patient was diagnosed with the first-known case of both PGM1-CDG and Leigh syndrome. Authors note that this study underlines the importance of considering the effects of multiple disease-causing variants in patients with complex clinical presentation.

Characterizing Diagnostic Delays in Metachromatic Leukodystrophy.

This summary is based on a paper published in the Journal of Inherited Metabolic Disease on June 2, 2025.

Metachromatic leukodystrophy (MLD) is a rare inherited disorder that causes progressive damage to the nervous system. The subtypes of MLD are defined by the onset of neurodegeneration, but less is known about the earliest features of this inborn error in metabolism.

In this study, researchers found that many children experience subtle early features in the months to years prior to diagnosis. The early medical journeys of children were mapped using two independent payor-system databases. Every medical encounter prior to diagnosis was captured. Across these cohorts, they found that children frequently presented within the medical system with signs and symptoms of disease, including early developmental delay, feeding issues, gallbladder problems, and abnormal eye movements. This work was complemented by similar findings from an MLD natural history study, which is supported through the GLIA-CTN.

Authors note that this study highlights early features of MLD and defines barriers to diagnosis, further supporting the need for early screening. By better understanding the barriers to diagnosis and characterizing how MLD begins, we can better define clinical monitoring guidelines in presymptomatic children and define ideal windows for intervention to improve outcomes. This work underscores the critical need for newborn screening to definitively diagnose children prior to disease onset.

Developing an Artificial Intelligence-Based Assessment of Telehealth Examinations in Myasthenia Gravis.

This summary is based on a paper published in the journal Muscle & Nerve on April 2, 2025.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles, causing disabling weakness. Although telemedicine is considered a positive tool for both MG patients and physicians, not much is known about its strengths and limitations for MG examinations.

In this study, researchers developed an artificial intelligence-based assessment of telehealth examinations in MG. The team studied video recordings of 51 patients with MG who completed two telemedicine-based examinations with neuromuscular experts. Researchers applied artificial intelligence algorithms including computer vision, speech analysis, and natural language processing to assess the reproducibility and reliability of the examinations.

Results showed that overall MG core examination scores were consistent across examiners. However, individual metrics showed up to 25% variability due to differences in examiner instructions, video recording limitations, and patient disease severity. Authors note that further refinement of this technology could enhance examiner training and reduce variability in clinical trial outcome measures.

Discussing the Impact of Rescue Therapy in Clinical Trials for Myasthenia Gravis.

This summary is based on a paper published in the journal Annals of Clinical and Translational Neurology on April 16, 2025.

Myasthenia gravis (MG) is a neuromuscular disorder caused by an autoimmune response which blocks or damages acetylcholine receptors in muscles, causing disabling weakness. Clinical trials for MG aim to evaluate whether a new therapy can improve patients’ symptoms. However, if a study participant experiences worsening symptoms, they typically receive existing therapies to improve their condition. This type of intervention, called “rescue therapy,” could lead to inaccurate information if not appropriately addressed.

In this review, researchers discuss the impact of rescue therapy in MG clinical trials. The team reviews strategies for incorporating rescue therapy in the design and statistical analysis of MG trials, shows how each strategy affects the interpretation of trial results, and suggests circumstances when each strategy may or may not be applicable to patients or physicians.

Authors note that rescue therapy should be considered during the planning phase of clinical trials before designing the statistical analysis, which can improve the robustness of the study and alignment with regulatory recommendations.

Exploring the Relationship Between Air Pollution and Primary Glomerular Diseases.

This summary is based on a paper published in the Clinical Kidney Journal on May 13, 2025. Primary glomerular diseases are a group of conditions that affect kidney function by attacking the glomeruli, which are kidney structures responsible for filtering the blood and removing waste in urine. Recent studies suggest that air pollution contributes to the onset and progression of chronic kidney disease and, specifically, glomerular disease.

In this review, researchers summarize the major sources and components of air pollution, the relationship between air pollution exposure and chronic kidney disease, and the impact of air pollution on the progression of primary glomerular diseases. The team highlights important gaps in knowledge and the need for future collaborative work involving environmental scientists, epidemiologists, and nephrologists.

Authors note that air pollution exposure represents a potentially modifiable risk factor for chronic kidney disease progression that can be addressed by regulatory action, personal behaviors, and intervention to prevent or limit exposure.
