Quizplus · Accepted Answer

Muscular dystrophy is a group of genetic disorders that cause progressive muscle weakness and degeneration. The most common type of muscular dystrophy is Duchenne muscular dystrophy, which is caused by a mutation in the gene that encodes the protein dystrophin. Dystrophin is a protein that helps to stabilize the muscle fibers. Without dystrophin, the muscle fibers become weak and damaged, leading to progressive muscle weakness and degeneration.
