Abstract
- X-linked Charcot-Marie-Tooth (CMTX) disease is a clinically heterogeneous hereditary motor and sensory neuropathy. The X-linked inheritance showed an absence of male-to-male transmission and a more severe disease phenotype in affected males compared to that in affected female. A missense mutation, Cys168Arg, was found in connexin 32 gene (Cx32/GJB1) from a patient with CMTX neuropathy. The familial history of this patient also suggested that the disease is X-linked CMT. Thus, we report a CMTX family having the novel Cys168Arg mutation in the Cx32 gene.
