What Causes Muscular Dystrophy?

MD is caused by changes (mutations) in the genes responsible for the structure and functioning of a person’s muscles.

The mutations cause changes in the muscle fibres that interfere with the muscles’ ability to function. Over time, this causes increasing disability.

The mutations are often inherited from a person’s parents. If you have a family history of MD, your GP may refer you for genetic testing and counselling to evaluate your risk of developing the condition or having a child with MD and to discuss the options available to you.
