DMD and Duchenne muscular dystrophy: DMD is the most prevalent muscular dystrophy (one in 3500 male births) due to a genetic mutation that leads to the complete or partial deficiency of dystrophin and, ultimately after several degeneration/regeneration cycles, leads to the subsequent replacement of skeletal muscle fibers by fat and connective tissue [98,146,147,148,149,150,151,152,153].
