Specific genetic cue for sudden cardiac death syndrome found

Researchers have found a specific genetic flaw that is connected to sudden death due to heart arrhythmia -- a leading cause of mortality for adults around the world. While a number of genes have been linked with arrhythmias, new researcher has uncovered that the functional impairment of a gene called KCNE2 underlies a multisystem syndrome that affects both heart rhythm and blood flow and can activate chemical triggers that can cause sudden cardiac death.
