Muscular dystrophy (MD) is an umbrella term used to describe a group of over 30 genetic conditions that cause progressive, irreversible muscle weakness and wastage. MD is part of a wider group of over 75 neuromuscular conditions (NMCs) - disorders that impair the functioning of nerves that control the voluntary muscles (e.g. muscles in the arms and legs. Muscular dystrophies are caused by mutations affecting various genes that code the proteins responsible for the structure and function of the muscles, making them weaker, fragile and susceptible to damage. This leads to progressive disability.
