Case Discussion

Hereditary motor sensory neuropathy (HMSN) also known as Charcot-Marie-Tooth (CMT) disease is a spectrum of genetic disorders caused by specific mutations in several myelin genes that lead to defects in myelin structure, maintenance, and formation.

Treatment is supportive for most inherited neuropathies and often requires arranging bracing and supportive devices in addition to routine health maintenance to minimize risk of secondary neuropathies from weight gain, diabetes, thyroid disease, or excessive alcohol consumption.
