Duchenne Muscular Dystrophy
Taken from Duchenne.Com
Duchenne muscular dystrophy (DMD) is a rare genetic disease that primarily affects males, but, in rare cases, can also affect females. 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. 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.
