Clinical features of hypertrophic cardiomyopathy caused by an Arg278Cys missense mutation in the cardiac troponin T gene.
To further examine the genetic and clinical features of hypertrophic cardiomyopathy caused by mutations in the cardiac troponin T (cTnT) gene, we screened 143 probands from our hypertrophic cardiomyopathy population for mutations in this gene. We report that the Arg278Cys missense mutation in the cTnT gene had a different clinical presentation in 2 different families and was associated with a clinical profile that deviates from what is currently expected for cTnT gene mutations.
