Specific genetic cue for sudden cardiac death syndrome found
While a number of genes have been linked with arrhythmias, UC Irvine's Geoffrey Abbott and his colleagues discovered 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.
"With these findings, we can now explore improved early detection and prevention strategies for people who are at higher risk of sudden cardiac death, such as those with diabetes," said Abbott, a professor of pharmacology and physiology & biophysics in the UC Irvine School of Medicine.
