Hypertrophic form of peroneal muscular atrophy (PMA): unusual nerve conduction results

A family with a hypertrophic form of peroneal muscular atrophy (PMA) was studied with typical clinical and electrophysiological abnormalities in the propositus and her child. The propositus' father was asymptomatic and slowing of nerve conduction velocities was limited to the peroneal nerves. Actual parentage was confirmed by 22 different serologic and electrophoretic marker systems.
