In our patients, we did not find any variant in the LMNA gene, but this could be partially related to the fact that no patient presented evidence of atrioventricular conduction block on ECG and no patient considered for or on the waiting list for heart transplantation has been included (even though almost half of our patients presented left bundle branch block and 35% presented nonsustained ventricular tachycardia, features also common in LMNA pathogenic variants carriers with DCM) [5]. The gene discussed is LMNA; the disease is Left bundle branch block.
