A novel PMP22 mutation Ser22Phe in a family with hereditary neuropathy with liability to pressure palsies and CMT1A phenotypes.
We describe a Cypriot family in which some family members presented with episodes of pressure palsies, while other family members had a slowly progressive chronic polyneuropathy typical of the Charcot-Marie-Tooth type 1 phenotype. All family members were evaluated clinically, with nerve conduction studies, and with genetic testing. In all affected individuals there was clinical and electrophysiological evidence of diffuse demyelinating sensorimotor polyneuropathy and a novel point mutation in the PMP22 gene (Ser22Phe) was identified.
