Mutations in the Genes for Cardiac Troponin T and α-Tropomyosin in Hypertrophic Cardiomyopathy

Abstract
Familial hypertrophic cardiomyopathy can be caused by mutations in the genes for β cardiac myosin heavy chain, α-tropomyosin, or cardiac troponin T. It is not known how often the disease is caused by mutations in the tropomyosin and troponin genes, and the associated clinical phenotypes have not been carefully studied.
