Muscular dystrophy SNOMEDCT_US:193225000 Muscle biopsy shows dystrophic changes HP:0003560 Muscular dystrophy can be demonstrated by muscle biopsy. SNOMEDCT_US:73297009 HP:0003793 HP:0003741 The term dystrophy means abnormal growth. However, muscular dystrophy is used to describe primary myopathies with a genetic basis and a progressive course characterized by progressive skeletal muscle weakness and wasting, defects in muscle proteins, and histological features of muscle fiber degeneration (necrosis) and regeneration. If possible, it is preferred to use other HPO terms to describe the precise phenotypic abnormalities.
