General Discussion

Becker muscular dystrophy is in the category of inherited muscle wasting diseases caused by a gene abnormality (mutation) that results in deficient or abnormal production of the dystrophin protein (dystrophinopathies). The abnormal gene is called DMD and is located on the X chromosome. Becker muscular dystrophy follows x-linked recessive inheritance so it mostly affects males, but some females are affected. Becker muscular dystrophy usually begins in the teens or early twenties and symptoms vary greatly between affected individuals. Muscle deterioration progresses slowly but usually results in the need for a wheel chair. Muscles of the heart deteriorate (cardiomyopathy) in some affected individuals, and this process can become life-threatening. Learning disabilities involving visual abilities may be present.
