Cardiac muscle is also affected by dystrophin loss and often leads to dilated cardiomyopathies [3, 4].Typically, cardiomyopathy begins in the first decade of life and evolves with progressive replacement of the myocardium by fibrous and fatty connective tissue resulting in end-stage dilated cardiomyopathy, which is a major cause of death in DMD patients [5]. The gene discussed is DMD; the disease is dilated cardiomyopathy.
