Charcot–Marie–Tooth (CMT) disease is a group of hereditary disorders affecting the motor and sensory nerves of the peripheral nervous system. CMT patterns of inheritance include dominant, recessive, and X-linked disorders. Charcot–Marie–Tooth disease, type 1B (CMT1B, OMIM 118200) is an autosomal dominant neuropathy caused by mutations in myelin protein zero (MPZ, OMIM 159440), a structural protein of peripheral myelin. Most causative MPZ mutations are missense sequence variants; however, recent clinical reports have described cases of CMT1B caused by increased dosage of the MPZ gene, with over-expression of the MPZ protein suspected to be causative of the disorder. We report an unusual case of early onset de novo CMT1B, caused by amplification of a familial, apparently benign, MPZ duplication.
