Highlights a new study showing that a cTnT missense mutation disrupts energy metabolism, explaining sudden cardiac death without significant hypertrophy in familial hypertrophic cardiomyopathy.
It has long been noted that while patients with familial hypertrophic cardiomyopathy due to cardiac troponin T (cTnT) mutations often suffer sudden cardiac death, they do not develop significant ventricular hypertrophy, suggesting that a distinct cellular mechanism apart from alterations in myocardial contractility is responsible. A new study has revealed that a single missense mutation in cTnT causes a striking disruption to energy metabolism, leading to cardiomyopathy.
