rs10757274 is a SNP located in chromosomal region 9p21; to date (2009), it is the strongest genetic predictor of early myocardial infarction (heart attack) discovered so far. SNPs in this region are also associated with increased risk of stroke, abdominal aortic aneurysm (AAA), and intracranial aneurysm.
Based on a large (20,000+) study primarily of Caucasian females, it appears that on its own, this single SNP does not improve on the discrimination or classification of predicted heart disease risk achieved by traditional risk factors, high-sensitivity C-reactive protein, and a family history of premature myocardial infarction.

rs10757274 and rs2383206 can double the risk of heart disease. About one in every four Caucasians are thought to carry the gene variants. rs10757278 in the same region has been linked to diabetes
