Dystrophin gen mutation
WebThe dystrophin gene is the largest gene identified so far, covering more than 2.5 megabases (Mb), and contains at least 79 exons; the high spontaneous mutation rate is a reflection of the large gene size. Dystrophin is primarily expressed in skeletal, cardiac, and smooth muscle cells, with smaller amounts expressed in the brain and retina. http://compbio.berkeley.edu/people/ed/rust/Dystrophin.html

WebBoth forms of MD are caused by mutations in the dystrophin gene, a large (2.6Mb) gene comprised of 97 exons. The dystrophin protein plays an important structural role as part of a large complex in muscle fiber membranes. When dystrophin is missing or non-functional, the entire complex is compromised, leading to degeneration of muscle tissue.
