CC -!- SUBUNIT: Myosin is an hexamer of 2 heavy chains and 4 light CC chains. CC -!- DISEASE: Defects in MYL2 are the cause of familial hypertrophic CC cardiomyopathy type 10 (CMH10) [MIM:608758]; also designated FHC CC or HCM. Familial hypertrophic cardiomyopathy [MIM:192600] is a CC heart disorder characterized by ventricular hypertrophy, which is CC usually asymmetric and often involves the interventricular septum. CC The prevalence of the disease in the general population is 0.2%. CC FHC is clinically heterogeneous, with inter- and intrafamilial CC variations ranging from benign to malignant forms with high risk CC of cardiac failure and sudden cardiac death. CC -!- DISEASE: Defects in MYL2 are the cause of hypertrophic CC cardiomyopathy with mid-left ventricular chamber type 2 (MVC2) CC [MIM:608758]. MVC2 is a very rare variant of familial hypertrophic CC cardiomyopathy, characterized by mid-left ventricular chamber CC thickening. CC -!- MISCELLANEOUS: This chain binds calcium. CC -!- SIMILARITY: Contains 3 EF-hand domains. CC -!- WEB RESOURCE: NAME=Familial hypertrophic cardiomyopathy mutation CC database; CC URL="http://www.angis.org.au/Databases/Heart/heartbreak.html".
