(HealthDay News) -- Two research teams have each identified genetic material strongly associated with a significantly increased risk of heart disease.
A test focused on the genetic variants, located on chromosome 9, might identify people at high risk of heart attack. About one in every four Caucasians are thought to carry the gene variants, and a test to spot those at risk could be available by the end of this year, the head of one research group said.
The discoveries are even more interesting, because the same region has recently been strongly implicated in bumping up diabetes risk.
"This is an important finding, because it was replicated in different populations around the world," added Canadian scientist Dr. Ruth McPherson, director of the Ottawa Heart Institute's lipid clinic and lipid research laboratory, who led one research effort.
The two separate reports, published in the online edition of the journal Science, do not pinpoint specific genes. Instead, they cite what are called "single nucleotide polymorphisms" (SNPs) -- slight variations in the sequence of units that make up the molecule of DNA that carries genetic information.
