ABSTRACTMany cases of cardiomyopathy have a genetic component: 90% of cases of hypertrophic cardiomyopathy are familial, and genetic factors may be responsible for 30% to 50% of cases of dilated cardiomyopathy. Clinical genetic testing for hypertrophic cardiomyopathy is becoming available, with significant implications for the clinician. This article gives an overview of how these genetic discoveries were made and how these new insights from genetics will affect clinical practice.
