EMD and cardiomyopathy: In 1994, human EMD gene encoding for emerin was first identified as the causative gene for X‐linked Emery–Dreifuss muscular dystrophy (X‐EDMD), now assigned to the subtype EDMD type 1 (EDMD1), which is classically characterized by progressive muscle dystrophy, early joint contractures and cardiomyopathy with conduction abnormalities.3, 4, 5
