Charcot-Marie-Tooth type 1A Patient with a Novel Frame Shift Mutation (Ala106fs) in the PMP22 Gene

ABSTRACT

Charcot-Marie-Tooth disease (CMT) with hearing impairment is a clinically distinct rare entity described in a few families, usually with a demyelinating neuropathy. The molecular basis for this disease has not been established with certainty. Audiological evaluation has revealed auditory neuropathy in the affected individual. We report a CMT1A family with sensorineural hearing loss and a novel frame shift mutation Ala106fs (318delT) in the PMP22 gene.
