Study of Sudden Cardiac Death Exposes Limits of Genetic Testing

August 19, 2016

(NPR) – Scientists have discovered that a common cause of sudden heart death has been misunderstood because researchers didn’t appropriately account for racial differences in their studies. The findings, published online Wednesday in the New England Journal of Medicine, have implications far beyond this particular inherited disease, called hypertrophic cardiomyopathy, or HCM. Researchers say the results also sound a cautionary note for many other illnesses that have been identified through genetic markers.
