Altered gene protects some African-Americans from coronary artery disease
Date:1/27/2011

A team of scientists at Johns Hopkins and elsewhere has discovered that a single alteration in the genetic code of about a fourth of African-Americans helps protect them from coronary artery disease, the leading cause of death in Americans of all races.

Researchers found that a single DNA variation - having at least one so-called guanine nucleotide in a base pair instead of a combination without any guanine - on a gene already linked to higher risk of coronary disease in other races is linked in blacks to decreased risk. Specifically, the study showed that otherwise healthy African-American men and women with the alternative genetic code had a fivefold reduction in the likelihood that their arteries would narrow or clog.

For African-Americans who inherited two copies of the guanine gene variant, one from each parent, the risk reduction was even more dramatic. They were 10 times less likely to have coronary heart disease, which disproportionately afflicts a greater number of African-Americans than whites or any other ethnic group. Nearly 17 million Americans have an arterial problem plaguing the heart, causing a half-million deaths, annually.

"What we think we have here is the first confirmed hereditary link to cardiovascular disease among African-Americans and it is a protective one," says senior study investigator and health epidemiologist Diane Becker, M.P.H., Sc.D. "This newly found link in African-Americans was not only protective instead of harmful but was also found at a precise location on gene CDKN2B, a gene close to the single base pair modification tied to other increased risk of coronary artery disease in other races."

Becker emphasizes that only an estimated quarter of blacks have the protective CDKN2B code, and only 6 percent have two copies, so "while a lot of African-Americans have this protective genetic modification, most do not." Advance testing for the genetic marker, she says, could ultimately in the
