Question

Quizplus · Accepted Answer

Duchenne's muscular dystrophy is caused by a mutation in the gene that codes for dystrophin, a protein important in maintaining muscle cell membrane stability. This gene is located on the X chromosome, so the condition is X-chromosomal recessive. It typically manifests in early childhood and progressively weakens the muscles, leading to eventual loss of mobility and function.
