Mutations in the lamin A/C (LMNA) gene have been associated with both cardiac and skeletal muscle abnormalities. Cardiac manifestations in LMNA cardiomyopathy have a variable age of onset and range from mild to life-threatening. We describe a case series illustrating manifestations of LMNA mutation in a single family with an extensive history of cardiac disease, including sudden cardiac death, and the implications for diagnosis and management. This discussion highlights potential presentations of LMNA mutations and the importance of genetic testing in patients with a family history of conduction abnormalities.
