Cardiomyopathies due to dystrophin (DMD) variants classically mimic a posterior, inferior, and/or lateral myocardial infarction, with abnormal Q waves in leads I, aVL, and V6, or in leads II, III, and aVF, together with high-voltage R waves in leads V1 and V2 [58]. This evidence concerns the gene DMD and myocardial infarction.
