According to WebMD,[1] Charcot-Marie-Tooth Disease (abbreviated CMT) is "a group of disorders in which the motor and/or sensory peripheral nerves are affected, resulting in muscle weakness and atrophy, as well as sensory loss. These manifestations occur first in the distal legs and later in the hands. The nerve cells in individuals with this disorder are not able to send electrical signals properly because of abnormalities in the nerve axon or abnormalities in the insulation (myelin) around the axon. Specific gene mutations are responsible for the abnormal function of the peripheral nerves. Charcot Marie Tooth disease can be inherited in an autosomal dominant, autosomal recessive or X-linked mode of inheritance."
