Mechanisms of the pathogenesis of troponin T-based familial hypertrophic cardiomyopathy.

Abstract excerpt

Mutations in cardiac troponin T (cTnT) cause hypertrophic cardiomyopathy characterized by comparatively little cardiac hypertrophy, but a high incidence of sudden cardiac death. Transgenic mice modeling this disease have smaller cardiomyocytes, leading to smaller hearts. However, different mutations in cTnT have distinct phenotypes with respect to fibrosis, induction of molecular markers, and systolic function....
