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 MID LEFT VENTRICULAR CC CHAMBER (MVC) THICKENING, A VERY RARE PHENOTYPE, EVEN AMONG CC HYPERTROPHIC CARDIOMYOPATHY (HCM) POPULATION. CC -!- DISEASE: DEFECTS IN MYL2 ARE ONE OF THE CAUSES OF FAMILIAL CC HYPERTROPHIC CARDIOMYOPATHY (FHC). CC -!- MISCELLANEOUS: THIS CHAIN BINDS CALCIUM. CC -!- SIMILARITY: TO OTHER EF-HAND CALCIUM BINDING PROTEINS.
