"THURSDAY, Dec. 3 (HealthDay News) -- New research points to the possibility of a genetic link between vitamin D and heart disease. People with high blood pressure who had a gene variant that reduces vitamin D activation in the body were found to be twice as likely as those without the variant to have congestive heart failure, the study found. The finding may lead to a way to identify people at increased risk for heart disease, according to Robert U. Simpson, an assistant professor of pharmacology at the University of Michigan Medical School and his research colleagues. They analyzed the genetic profiles of 617 people. One-third had hypertension, one-third had hypertension and congestive heart failure, and the remaining third served as healthy controls. The researchers found that a variant in the CYP27B1 gene was associated with congestive heart failure in people with hypertension. The study is in the November issue of Pharmacogenomics."
