Progressive peroneal muscular atrophy (Charcot-Marie-Tooth disease) associated with beta-thalassemia trait and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. A clinical and nerve biopsy case.

The case of a 22 year old woman presenting progressive peroneal muscular atrophy (PMA) is described. Electrophysiological and pathological studies demonstrated features of hereditary motor and sensory neuropathy -HMSN- type I. Laboratory findings showed two erythrocytic defects: beta-thalassemia trait and a glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Unlike the past, these inherited disorders are associated with PMA.
