What is Duchenne?
Muscular dystrophies are a group of diseases that cause weakness and degeneration of the skeletal muscles. At the CHEO Research Institute, much of our research is focused on Duchenne Muscular Dystrophy (DMD), one of nine types of muscular dystrophy. DMD is a genetic disorder characterized by progressive muscle degeneration and weakness. DMD is caused by an absence of dystrophin, a protein that helps keep muscle cells intact. The disease primarily affects boys and in rare cases can affect girls. The past decade has seen tremendous advances in the diagnosis and treatment of DMD. These advances have led to an improved outlook for those living with the condition, translating into heightened optimism within the DMD community.
