Wikimedia Commons has media related to Duchenne muscular dystrophy. Due to defects in this assembly, contraction of the muscle leads to disruption of the outer membrane of the muscle cells and eventual weakening musculalres wasting of the muscle. In muscular dystrophy, abnormal genes mutations interfere with the production of proteins needed to form healthy muscle.
Disruption of the blood-brain barrier has been seen to be a noted feature in the development of DMD.
