Duchenne muscular dystrophy or Psendo Hypertroplnic Muscular Dystrophy is heterogenous group of inherited disorder C graddal degeneration of muscle fibres. It is Inheritance sex linked disease and boys are sufferer while girls are carrier. Patient dies in 2^nd /3^rd decade of life due to pulmoray infection and cardionyopahy.

Keywords: X linked disease, mutation,  Grower’s Sing,  Baker Muscular dystrophy, serum creatine kinase, EMG, muscle Biopsy.
