Distal Myopathy

Mutations in the MATR3 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. Her father, deceased some years before, presented a similar distal myopathy phenotype, while her 20-year-old son is asymptomatic. Myopathic changes with vacuolization were observed in muscle biopsy from the propositus. These results, together with the peculiar clinical picture, lead to MATR3 gene sequencing, which revealed a heterozygous p.S85C mutation in the propositus. The same mutation was found in her son. Over a 5-year follow-up, progression is mild in the propositus, while her son remains asymptomatic. Clinical, radiological, and pathological data of our propositus are presented and compared to previously reported cases of VCPDM. VCPDM turns out to be a quite homogenous phenotype of late-onset myopathy associated to p.S85C mutation in MATR3 gene. MATR3-related pathology, encompassing myopathy and motor neuron disease, represents an illustrative example of multisystem proteinopathy (MSP), such as other diseases associated to mutations in VCP, HNRNPA2B1, HNRNPA1, and SQSTM1 genes. The present report contributes to a further characterization of this still poorly understood pathology and points out the diagnostic utility of muscle biopsy in challenging cases.
