Detailed explanation-1: -It is caused by a genetic mutation on one of the mother’s X chromosomes, and researchers have identified some of the affected genes. Duchenne muscular dystrophy is caused by a genetic problem in producing dystrophin, a protein that protects muscle fibers from breaking down when exposed to enzymes.
Detailed explanation-2: -In skeletal and cardiac muscles, dystrophin is part of a group of proteins (a protein complex) that work together to strengthen muscle fibers and protect them from injury as muscles contract and relax.
Detailed explanation-3: -The dystrophin complex stabilizes the plasma membrane of striated muscle cells. Loss of function mutations in the genes encoding dystrophin, or the associated proteins, triggers instability of the plasma membrane and myofiber loss.
Detailed explanation-4: -Duchenne’s muscular dystrophy results from alterations in the dystrophin protein, which is a very large intracellular protein that normally associates with other proteins (so-called dystrophin-associated proteins) at the inner surface of the plasma membrane of muscle cells.
