Cardiovascular researchers at the University of Cincinnati have identified a genetic variant in a cardiac protein that can be linked to heart rhythm dysfunction. This is the first genetic variant in a calcium-binding protein (histidine-rich calcium binding protein) found to be associated with ventricular arrhythmias and sudden cardiac death in dilated cardiomyopathy patients, opening up new possibilities for treatment.
