|Charcot Marie Tooth Disease Inherited Peripheral Neuropathy|
Charcot Marie Tooth Disease (CMT) is a group of disorders that cause a peripheral neuropathy, impairing the long nerves that go to the feet and hands. Due to the problems with the peripheral nerves, people with CMT have muscle weakness and sensory loss that impairs their physical abilities. CMT affects approximately 1 in 2500 people and is caused my mutations in over 70 different genes. Models exist for many sub-types of CMT that have led to an increased understanding of the biological basis for these disorders. These advances have also made rational therapies for CMT a realistic possibility. However, clinical trials have been limited in CMT by a combination of lack of natural history data for many subtypes, a lack of outcome measures that can detect change in a short period for slowly progressive forms of CMT, and a lack of outcome measures for young children with CMT.
In order to develop treatments based on the biological advances in the inherited neuropathies, it is necessary to have measured the natural history of the various disorders. It is only by knowing the natural history that one understands the onset of clinical symptoms, the rate of progression, and the ultimate prognosis of these diseases. For these reasons, the INC has dedicated much of its effort to develop sensitive outcome instruments, including PRO tools, to measure the natural history of CMT. It is the investigators goal to establish such an instrument for overall impairment for use in both natural history analysis and clinical trials. To develop and validate this instrument, the investigators will be asking people who have CMT to complete two questionnaires, the DSI and the HMSN-R-ODS. These relate to overall symptom impairment due to CMT. These instruments may be used to help us understand the overall progression of CMT and will ultimately help with clinical trials when they are available for the various forms of CMT.

Participants evaluated at INC sites
Participants being evaluated at the INC sites will participate in both the DSI and HMSN-R-ODS by completing these PROs during their visit.

- Disability Severity Index [ Time Frame: Approximately 30 minutes ]The DSI asks the subject to provide information about how disability is reflected in general by equipment required for mobility. Therefore, the DSI asks the subject if a person in general was wearing AFOs (braces) for mobility, what level of disability would that reflect using both a quantitative measurement of score and a verbal method of scoring (none, mild, moderate, severe). These questions do not apply to the participant themselves, just in general how disabled they believe a person to be based on the mobility assistive devices that that person requires. Then a research team member will complete the last page which specifically asks about what that subject is using for mobility.
- Hereditary Motor and Sensory Neuropathy Overall Disability Scale (HMSN-R-ODS) [ Time Frame: Approximately 30 minutes ]The HMSN-R-ODS is a functional score about the subject asking about their daily activities and overall health. Questions are grouped in various sections and include: Changing and holding body positions; walking and movement; movement by transport; carrying, moving, or handling objects; self-care; household activities and duties; taking care (daily tasks) - general; meeting other people; work, study, and hobbies. These questions relate specifically to the subject and ask how they can perform these various activities with little to severe difficulty.
