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. WebThese mutations prevent cells from producing the dystrophin protein which is needed for muscle function. What is a nonsense mutation? Genes are the instructions that allow a cell to make a protein and the dystrophin gene is the biggest in human cells – the DNA code is more than 10,000 letters long. A nonsense mutation is a special type of ...
