WTF is Charcot-Marie-Tooth Disease (CMT)?

(shar-ko¯’ mä-re´ tooth)

Charcot–Marie–Tooth disease (CMT) is a hereditary motor and sensory neuropathy of the peripheral nervous system characterized by progressive loss of muscle tissue and touch sensation across various parts of the body.

This disease is the most commonly inherited neurological disorder affecting about one in 2,500 people. It is named after those who discovered it: Jean-Martin Charcot, Pierre Marie, and Howard Henry Tooth.

Research: There is no known cure, but the Hereditary Neuropathy Foundation is diligently pursuing research for treatments and cures with their Global Registry for Inherited  Neuropathies, (GRIN) and Therapeutic Research In Accelerated Discovery, (TRIAD) programs.


Genes: There are over 100 known genes that cause either demyelination or axonal damage to the peripheral nerves which leads to muscle atrophy.
