Muscular dystrophies (DM) are inherited neuromuscular diseases caused by defects in several genes that result in loss of function, reduction or absence of proteins necessary for the proper functioning of muscle fibers. The consequence is a progressive degeneration of the muscle tissue and a strength deficit of variable size, distribution and time of appearance. There are many forms of dystrophies which are classified based on clinical criteria and the genetic defect. The most common form of developmental muscular dystrophy is Duchenne muscular dystrophy.
