Abstract: C h a r c o t- M a r i e - To o t h d i s e a s e ( C M T ) i s a heterogeneous group of inherited peripheral neuropathies; it is characterized by muscle weakness and wasting, as well as sensory dysfunction, that typically begins during adolescence and ultimately leads to lifelong disability. Occurring in ~1 in 2500 individuals, CMT is the most common hereditary neuromuscular condition and results from mutations in > 100 different genes. CMT is grouped into type 1 (CMT1), where demyelination and loss of nerve conduction velocity occur, type 2 (CMT2), where motor and sensory axons degenerate without loss of myelination/nerve conduction velocity, and intermediate CMT, where both demyelination and axon loss present alongside intermediate nerve conduction velocities.
