Duchenne muscular dystrophy epidemiology and demographics

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Fahimeh Shojaei, M.D.

Overview

The incidence of Duchenne muscular dystrophy is approximately 20 per 100,00 births worldwide. In 2010, the prevalence of Duchenne/ Becker muscular dystrophy was estimated to be 1.38 per 10,000 male individuals, ages 5 to 24 years. The mortality rate of Duchenne muscular dystrophy is 100%. The symptoms of Duchenne muscular dystrophy commonly presents in children younger than 5 years of age. Duchenne muscular dystrophy usually affects individuals of the Hispanic race. Non-Hispanic white or black individuals are less likely to develop DMD. Since the disease is X-link recessive, almost all of the patients are male but we may have some female carriers with symptoms as well.
