CMT decreases the ability of these nerves to carry motor commands to muscles, especially those furthest from the spinal cord located in the feet and hands. As a result, the muscles connected to these nerves eventually weaken
Charcot-Marie-Tooth disease (CMT) primarily affects the peripheral nerves, leading to muscle weakness and atrophy, especially in the feet and legs. It can cause sensory loss, resulting in decreased ability to feel pain or temperature changes, and may lead to foot deformities like high arches or hammertoes. Over time, individuals may experience difficulties with balance and coordination. The severity and specific symptoms can vary widely depending on the type of CMT.
CMT is caused by mutations in genes that produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. Although different proteins are abnormal in different forms of CMT disease, all of the mutations affect the normal function of the peripheral nerves. The gene mutations in CMT disease are usually inherited.
Jean- Martin- Charcot, Pierre Marie, and Howard Henry Tooth all discovered this disease
No, Charcot-Marie-Tooth disease (CMT) is not a type of muscular dystrophy. CMT is a hereditary neuropathy that affects peripheral nerves, leading to muscle weakness and atrophy, primarily in the limbs. In contrast, muscular dystrophies are a group of genetic disorders characterized by progressive muscle degeneration and weakness due to defects in muscle proteins. While both conditions involve muscle issues, they stem from different underlying causes and affect different parts of the nervous system.
Mutations in several genes cause the various types of CMT to occur. The most common form of the disorder, CMT1A, is caused by duplication in the peripheral myelin protein 22 (PMP22) gene.

They require therapy dogs since Charcot-Marie-Tooth disease has no cure and needs physical and occupational therapy.
Symptoms of Charcot Marie Tooth disease are lack of muscle, high arches in your feet and claw toes. Other diseases should be ruled out before this is locked in as a diagnosis.
X-linked Charcot-Marie-Tooth disease (CMTX) is caused by a defect in connexin 32. This protein forms connections between adjacent cells, allowing ions to flow between them.
