Mol. Med. 76:208-214(1998). CC -!- SUBUNIT: Myosin is an hexamer of 2 heavy chains and 4 light CC chains. CC -!- DISEASE: Defects in MYL2 are a cause of hypertrophic CC cardiomyopathy, mid-left ventricular chamber type (MVC) CC [MIM:160781]. MVC is a very rare phenotype, even among CC hypertrophic cardiomyopathy population. Defects in MYL2 are one of CC the causes of familial hypertrophic cardiomyopathy (FHC). CC Hypertrophic cardiomyopathies are marked by ventricular CC hypertrophy, particularly of the left ventricul and often CC involving the interventrivular septum with diastolic dysfunction CC and manifest as impaired ventricular filling. CC -!- MISCELLANEOUS: This chain binds calcium. CC -!- SIMILARITY: Contains 1 EF-hand calcium-binding domain.
