What is Duchenne / Becker Muscular Dystrophy?
Duchenne and Becker are from a group of Muscular Dystrophies known as Dystrophinopathies. A fault in a particular gene (dystrophin) carried on the X chromosome leads to the formation of a faulty protein in muscle fibres. This protein, also called dystrophin, is absent or severely abnormal in Duchenne muscular dystrophy. In Becker muscular dystrophy a milder fault makes the dystrophin molecule smaller or less abundant than normal.
