In terms of impact on heart conditions and development of dilated cardiomyopathy, impairment of the lamin A/C gene is a well-known factor (50) and results in conduction problems, arrhythmias, atrioventricular block and sudden cardiac death (51–55) with at least 260 LMNA mutations having been linked to cardiac diseases (56). This evidence concerns the gene LMNA and dilated cardiomyopathy.
