This study will assess the serum NT-3 levels in those with a peripheral neuropathy diagnosis which will help to determine the therapeutic levels of NT-3 in subjects that will receive AAV1.NT-3 gene therapy in a future study. This study also aims to define the natural history of any type of Charcot-Marie Tooth Disease (CMT), better define the rate of disease progression and skeletal muscle involvement. Another aim is to generate a registry of well-characterized CMT patients who may be candidates for future trials.
This study will assess the serum NT-3 levels in individuals with the diagnosis of peripheral neuropathy or any type of Charcot-Marie-Tooth Neuropathy (CMT) and correlate this with function.
