Distal myopathy is a group of heterogeneous disorders affecting predominantly distal Muscles usually appearing from voting to late adulthood with very rare cardiac complications. We report a 27-year-old man characterized clinically by distal myopathy and dilated cardiomyopathy, pathologically by lipid storage, and genetically by a PNPLA2 mutation. The patient developed weakness in his lower legs and fingers at age 20 years. Physical examination at age 27 years revealed muscle weakness and atrophy predominantly in lower legs and hands, and severe dilated cardiomyopathy. The patient had a homozygous four-base duplication (c.475_478dupCTCC in exon 4 of PNPLA2. (C) 2008 Elsevier B.V. All rights reserved.
