Inherited and de novo mutations in the cardiac actin gene cause hypertrophic cardiomyopathy.

Abstract excerpt

Mutations in genes encoding sarcomeric proteins cause hypertrophic cardiomyopathy (HCM). The sarcomeric protein actin plays a central, dual role in cardiac myocytes, generating contractile force by interacting with myosin and also transmitting force within and between cells. Two missense mutations in the cardiac actin gene (ACTC), postulated to impair force transmission, have been associated with familial dilated...
