Charcot-Marie-Tooth Disease Type 1A
Type of disease: Rare conditions
Charcot-Marie-Tooth disease type 1A (CMT1A) is a type of inherited neurological disorder that affects the peripheral nerves. Affected individuals experience weakness and wasting (atrophy) of the muscles of the lower legs beginning in adolescence; later they experience hand weakness and sensory loss. CMT1A is caused by having an extra copy (a duplication) of the PMP22 gene. It is inherited in an autosomal dominant manner. Treatment for this condition may include physical therapy; occupational therapy; braces and other orthopedic devices; orthopedic surgery; and pain medications.
