Duchenne muscular dystrophy typically results from _______ dystrophin.

Question

Quizplus · Accepted Answer

Duchenne muscular dystrophy is caused by deletions or mutations in the dystrophin gene. This gene codes for a protein called dystrophin, which is vital for maintaining the structure and stability of muscle fibers. Without enough dystrophin, muscle fibers weaken and degenerate, leading to the symptoms of muscular dystrophy. Point mutations, duplications, translocations, and inversions can all potentially affect the function of the dystrophin gene, but deletions are the most common cause of Duchenne muscular dystrophy.
