Miyoshi Muscular Dystrophy 1; Mmd1

Description

Miyoshi muscular dystrophy is an autosomal recessive skeletal muscle disorder characterized by onset in young adulthood of distal muscle weakness affecting the upper and lower limbs but sparing the intrinsic hand muscles. Muscle weakness and atrophy particularly affects the gastrocnemius and soleus muscles, and can later spread to involve the thigh and gluteal muscles. Patients showed impaired tiptoe standing, difficulty in climbing stairs, and difficulty walking, but usually remain ambulatory. Serum creatine kinase is increased and muscle biopsies show myopathic and dystrophic changes with necrosis (summary by Miyoshi et al., 1986). Genetic Heterogeneity of Miyoshi Muscular DystrophyMiyoshi muscular dystrophy is a genetically heterogeneous disorder: MMD2 (OMIM ) has been mapped to chromosome 10p, and MMD3 (OMIM ) is caused by mutation in the ANO5 gene (OMIM ) on chromosome 11p14.See also Welander myopathy (OMIM ), an autosomal dominant form of late-onset distal myopathy.
