Becker muscular dystrophy (BMD) is caused by specific mutations in the DMD gene. The DMD gene gives instructions for making a protein called dystrophin. This protein helps stabilize and protect muscle fibers and may play a role in chemical signaling within cells. Mutations that lead to an abnormal "version" of dystrophin that keeps some of its function usually cause BMD. Muscle cells without fully functional dystrophin become damaged as muscles contract and relax with use. They then weaken and die over time, leading to the muscle weakness and heart problems in people with BMD.
