Genetic testing is used to confirm a diagnosis of Duchenne muscular dystrophy (DMD) and identifies the specific type of mutation.1,2 Knowing the mutation type can be helpful for medical management options and the possibility of enrolling into clinical trials.2 A genetic carrier screening test should be performed in female relatives of a boy or man who has been genetically confirmed to have DMD.1
