Charcot-Marie-Tooth (CMT) disease, also called hereditary motor and sensory neuropathy (HMSN), is a group of disorders characterized by a chronic motor and sensory polyneuropathy. Based on nerve conduction velocities, the disease can be divided into demyelinating CMT (CMT1), axonal CMT (CMT2) and intermediate CMT (CMTDI/CMTRI). Although more than 70 disease genes for CMT are known, a large number of affected individuals remain without a genetic diagnosis.
CMT1: Abnormal myelin, autosomal dominant
CMT2: Axonopathy, autosomal dominant
Intermediate form: Combination of myelinopathy and axonopathy in individual, autosomal dominant
CMT4: Either myelinopathy or axonopathy, autosomal recessive
CMTX: Axonopathy with secondary myelin changes, X-linked dominant
MNMN: Mononeuropathy of the median nerve mild
