Charcot-Marie-Tooth disease, Guadalajara neuronal type

This study tests a device called Walkasins, worn on the lower legs, that vibrates to give sensory feedback about foot pressure. The goal is to see if using it daily for six months improves balance and walking in 200 adults aged 55+ with peripheral neuropathy. Participants will do…

Researchers are building a global registry to collect patient-reported surveys, genetic test results, and medical records from people with Charcot-Marie-Tooth disease and related inherited neuropathies. The study is open to children and adults with a confirmed or suspected diagno…

This study aims to learn more about rare inherited disorders that affect the brain, spinal cord, muscles, and nerves. Researchers will collect medical history, perform exams, and run genetic tests on up to 3,500 participants. No new treatments are tested; the goal is to better un…

This study is collecting information from 4,000 adults with peripheral neuropathy (nerve damage) to better understand the condition. Researchers will combine standard tests with nerve ultrasound to see if it helps diagnose and track the disease. No new treatments are being tested…

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

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…
