I am so sorry,
CMT is an acronym for Charot-Marie-Tooth disease named after the discovers. Charcot (shahr-KOH)-Marie-Tooth disease is a group of inherited conditions that cause nerve damage. Inherited conditions pass down through families. This damage mainly is in the nerves of the arms and legs, called the peripheral nerves. Charcot-Marie-Tooth disease also is called hereditary motor and sensory neuropathy.

Charcot-Marie-Tooth disease causes smaller, weaker muscles. It also may cause trouble walking, and loss of feeling in the legs and feet. Some people cannot tense their muscles. Foot issues such as hammertoes and high arches are common. Symptoms most often begin in the feet and legs. But in time, they may affect the hands and arms.
