Explanation:  

Muscular dystrophy (MD) is a group of inherited genetic conditions that cause progressive weakness and the loss of muscle mass. MD is caused by mutations in genes responsible for muscle function. MD not only leads to problems in the muscular system but also may cause disorders of the central nervous system and the circulatory system (especially the heart). For example, Becker muscular dystrophy is a condition associated with arrhythmias and cardiomyopathies. Moreover, MD may lead to vision and speech problems, and result in irreversible structural brain changes.
