Is Duchenne muscular dystrophy common is a certain race?

Duchenne muscular dystrophy (DMD) affects all races and ethnic groups, but it is more common in males due to its X-linked recessive inheritance pattern. The incidence is estimated to be about 1 in 3,500 to 5,000 male births globally. While there is no specific racial predisposition, variations in genetic factors and access to healthcare may influence diagnosis and prevalence in different populations. Overall, DMD is considered a rare disorder regardless of race.
