The risk allele, rs10757278(G), shows an increased association for myocardial infarctions ("MI"; heart attacks) both in general and more specifically in so-called early onset MI. The odds ratio relative to rs10757278(A:A) "noncarrier" individuals for rs10757278(G;G) individuals is 1.64 (CI: 1.47-1.82), and for carriers of one risk allele, i.e. rs10757278(A;G) individuals, 1.26 (CI: 1.16-1.36). [PMID 17478679]
For early onset MI, the odds are slightly higher; homozygote rs10757278(G;G) individuals have an odds ratio of 2.02 (CI: 1.72-2.36), heterozygote rs10757278(A;G) individuals 1.49 (CI: 1.31-1.69) compared to noncarriers. To put it another way, men under the age of 50 and women under the age of 60 who are rs10757278(G:G) individuals have about twice the risk of having a heart attack compared to rs10757278(A:A) individuals. [PMID 17478679]
In an extension of the research reported above, the rs10757278(G) allele has been found to be associated with stroke as defined by abdominal aortic aneurysm (AAA; odds ratio 1.31, p=1.2x10e-12) and Intracranial Aneurysm (odds ratio 1.29, p=2.5x10e-6), but not with type-2 diabetes. The AA genotype appears to be protective, with 0.77x odds of developing abdominal aortic aneurysm as reported by DeCode. [PMID 18176561]

The association remained significant after adjusting for significant clinical covariates (P=0.001 to 0.024). We identified one risk haplotype (GGGG; P=0.017) and one protective haplotype (AAAA; P=0.007) for development of CAD. Further analysis suggested that the SNPs probably confer susceptibility to CAD in a dominance model (covariates-adjusted P=0.001 to 0.024; OR=2.37 to 1.54).
