Nervous System Diseases

Summary Summary

Charcot-Marie-Tooth disease is a group of disorders that affect the peripheral nerves, the nerves running from outside the brain and spine.^[1] Defects in many different genes cause different forms of this disease. Common symptoms may include foot drop, foot deformity, loss of lower leg muscle, numbness in the foot or leg, “slapping" gait (feet hit the floor hard when walking), and weakness of the hips, legs, or feet.^[1] There is currently no cure for Charcot-Marie-Tooth disease, but physical therapy, occupational therapy, braces and other orthopedic devices, pain medication, and orthopedic surgery can help manage and improve symptoms.^[2]

There are over 40 types of Charcot-Marie-Tooth disease. You can search for more information on a particular type of Charcot-Marie-Tooth disease from the GARD Home page. Enter the name of the condition in the GARD search box, and then select the type from the drop down menu.

Symptoms Symptoms

The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.

Signs and Symptoms	Approximate number of patients (when available)
Abnormality of the pharynx	Very frequent (present in 80%-99% of cases)
Abnormality of the voice	Very frequent (present in 80%-99% of cases)
Ataxia	Very frequent (present in 80%-99% of cases)
Decreased nerve conduction velocity	Very frequent (present in 80%-99% of cases)
Distal amyotrophy	Very frequent (present in 80%-99% of cases)
EMG abnormality	Very frequent (present in 80%-99% of cases)
Gait disturbance	Very frequent (present in 80%-99% of cases)
Impaired pain sensation	Very frequent (present in 80%-99% of cases)
