LMNA and familial dilated cardiomyopathy: Well-characterised inherited CMs include hypertrophic cardiomyopathy (HCM, e.g., MYH7 gene mutation; OMIM CMH), dilated cardiomyopathy (DCM, e.g., SGCD gene mutation; OMIM CMD), and arrhythmogenic cardiomyopathy (ACM, e.g., LMNA gene mutation), for which established clinical pathways are available for diagnosis and management [5].
