First Family of -Related Distal Myopathy From Italy: The Role of Muscle Biopsy in the Diagnosis and Characterization of a Still Poorly Understood Disease.

Mutations in the gene are associated to distal myopathy with vocal cord and pharyngeal weakness (VCPDM), as well as familiar and sporadic motor neuron disease. To date, 12 VCPDM families from the United States, Germany, Japan, Bulgary, and France have been described in the literature. Here we report an Italian family with a propositus of a 40-year-old woman presenting progressive bilateral foot drop, rhinolalia, and distal muscular atrophy, without clinical signs of motor neuron affection.
