What is Duchenne Muscular Dystrophy?
Duchenne muscular dystrophy, sometimes shortened to DMD or just Duchenne, is a rare genetic disease. It primarily affects males, but, in rare cases, can also affect females. Duchenne causes the muscles in the body to become weak and damaged over time, and is eventually fatal. The genetic change that causes Duchenne — a mutation in the DMD gene — happens before birth and can be inherited, or new mutations in the gene can occur spontaneously.
Duchenne is caused by a genetic mutation that prevents the body from producing dystrophin, a protein that muscles need to work properly. Without dystrophin, muscle cells become damaged and weaken. Over time, children with Duchenne will develop problems walking and breathing, and eventually the muscles that help them breathe and the heart will stop working. Duchenne is an irreversible, progressive disease. There is currently no cure for Duchenne.
