This study follows up to 10 children under 2 years old with acid sphingomyelinase deficiency (ASMD) who are already receiving olipudase alfa (Xenpozyme®) as part of their routine care. Researchers will monitor side effects and immune responses over 1 to 3 years. No new treatment …

This study collects medical information and biological samples (like blood or tissue) from up to 12,000 people with leukodystrophies—rare disorders that damage the brain's white matter. Researchers will use this data to find new genetic causes, develop biomarkers for future trial…

This observational study follows up to 5,000 people with Charcot Marie Tooth disease (CMT) types 1B, 2A, 4A, and 4C over five years. Researchers will measure symptoms, nerve function, and disability using special scales to understand how the disease changes over time. The goal is…

This study aims to find new genes that cause Charcot-Marie-Tooth disease (CMT) and discover why symptoms differ among people with the same genetic change. Researchers will analyze DNA from up to 1,050 participants to identify genetic modifiers and unknown causes. The goal is to b…

This study collects blood samples from 100 people with rare brain diseases like adrenoleukodystrophy and metachromatic leukodystrophy. Researchers will study immune cells called macrophages to see if they affect how the disease progresses. No treatment is given; the goal is to le…

This study looks at how well ankle-foot orthoses (AFOs) and surgical correction help people with Charcot-Marie-Tooth disease (CMT) and cavovarus foot deformity walk and keep their balance. Researchers will test 66 participants on stepping, walking speed, and balance confidence. T…

This study looks at how ultrasound images of the median nerve in the wrist relate to a person's ability to feel touch in carpal tunnel syndrome. Researchers will measure nerve size and texture with ultrasound and compare them to sensory tests like two-point discrimination. The go…

This study follows 240 patients with hereditary transthyretin amyloidosis with polyneuropathy (hATTR-PN) to monitor the long-term safety of the drug TEGSEDI. Researchers will compare patients who have taken TEGSEDI with those who have not, focusing on side effects like low platel…

This study is looking at 50 adults with a rare genetic nerve disorder called RFC1-ataxia or CANVAS, which causes problems with balance, coordination, and sensation. Researchers will take blood samples and skin biopsies over 12 months to measure markers of cell stress and damage. …

This study aims to learn more about rare disorders that affect how the body processes chemicals called pyrimidines and purines. These disorders can cause problems in the brain, blood, kidneys, and immune system, ranging from mild to life-threatening. Researchers will compare test…
