What is Charcot-Marie-Tooth disease (CMT)?

Charcot-Marie-Tooth (CMT) disease is one of the most common inherited neurological disorders, affecting approximately 1 in 2,500 people in the United States. The disease is named after the three physicians who first identified it in 1886 ― Jean-Martin Charcot and Pierre Marie in Paris, France, and Howard Henry Tooth in Cambridge, England. CMT, also known as hereditary motor and sensory neuropathy (HMSN) or peroneal muscular atrophy, consists of a group of disorders that affect the peripheral nerves. The peripheral nerves lie outside the brain and the spinal cord and supply the muscles and sensory organs in the limbs. The disorders that affect the peripheral nerves are called peripheral neuropathies.
