Abstract

Abstract: Cardiomyopathies caused by double gene mutations are rare but conferred a remarkably increased risk of end‐stage progression, arrhythmias, and poor outcome. Compound genetic mutations leading to complex phenotype in the setting of cardiomyopathies represent an important challenge in clinical practice, and genetic tests allow risk stratification and personalized clinical management of patients. We report a case of a 50‐year‐old woman with congestive heart failure characterized by dilated cardiomyopathy, diffuse coronary disease, complete atrioventricular block, and missense mutations in cardiac myosin‐binding protein C ( MYBPC3 ) and myopalladin ( MYPN ). We discuss the plausible role of genetic profile in phenotype determination.
