Charcot-Marie-Tooth disease- Type 1E


Charcot-Marie-Tooth disease, Type 1E: CMT is an inherited neurological disease characterized by the gradual degeneration of nerves which starts in the hands and feet and results in progressive numbness, muscle weakness and loss of function. Type 1E involves the usual CMT symptoms as well as deafness.

A definitive diagnosis for a specific type of CMT is established via genetic testing for most types. However, some genetic markers have not yet been identified, and a diagnosis can also be established via an electromyography examination (which shows that the velocity of nerve impulse conduction is decreased and the time required to charge the nerve is increased) and nerve biopsy.
