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.

Description
Spinal muscular atrophy (SMA) is a neuromuscular disease characterized by degeneration of motor neurons, resulting in progressive muscle atrophy and paralysis. The most common form of SMA is caused by mutations of the SMN gene, that encodes the SMN protein, which regulates snRNP assembly. Four types of SMA are recognized depending on the age of onset and the severity of the disease: type I (Werdning-Hoffman), type II (intermediate), type III (Kugeleberg-Welander) and type IV (adult form). Other forms of spinal muscular atrophy are caused by mutation of other genes, some known and others not yet defined.

DISEASE: Complex cortical dysplasia with other brain malformations
Entry
H01881 Disease
Name
Complex cortical dysplasia with other brain malformations
Description
Complex cortical dysplasia with other brain malformations (CDCBM) is a disorder of aberrant neuronal migration and disturbed axonal guidance. Patients exhibit mental retardation, strabismus combined with nystagmus, axial hypotonia, and spasticity. The severity of mental retardation ranged from mild to severe. Complex cortical malformations associated with mutations in tubulin and motor proteins of the kinesin genes have been reported.
