Summaries for Myopathy, Distal, 4

OMIM : 58 Williams distal myopathy is an autosomal dominant slowly progressive muscular disorder characterized by distal muscle weakness and atrophy affecting the upper and lower limbs. Onset occurs around the third to fourth decades of life, and patients remain ambulatory even after long disease duration. Muscle biopsy shows nonspecific changes with no evidence of rods, necrosis, or inflammation (summary by Duff et al., 2011). Mutation in the FLNC gene can also cause myofibrillar myopathy-5 (MFM5; 609524), which shows a different pattern of muscle involvement and different histologic changes. (614065)

MalaCards based summary : Myopathy, Distal, 4, is also known as williams distal myopathy, and has symptoms including calf muscle weakness An important gene associated with Myopathy, Distal, 4 is FLNC (Filamin C). Related phenotypes are cardiomyopathy and muscle weakness
