We reported a man and his son with Charcot-Marie-Tooth disease (CMT) type 2. Their age at onset was about 5 years. Their clinical examinations revealed muscle atrophy and weakness of both distal lower limbs, foot-drop, a reduction of the reflex in both Achilles tendons and sensory impairment of the glove and stocking type. Nerve conduction studies revealed remarkably low amplitude of compound muscle action potential compared to conduction velocity. The nerve biopsy of their sural nerves revealed loss of large myelinated fiber. We presumed that the clinical features of their disease were compatible with CMT2A or 2B. DNA analysis of our family members performed with microsatellite markers linked to the candidate regions of CMT2A and 2B, did not show apparent positive results. We speculate that this family was a novel gene locus of CMT type 2.
