The rs12526453 CC homozygotes (previously associated with increased risk of myocardial infarction) showed, in 2 independent samples, better long-term survival.
Besides the CAD/MI SNP at 9p21 (rs4977574, P = 3.1 × 10(-10)), two additional loci at ADAMTS7 (rs3825807, P = 6.5 × 10(-6)) and at PHACTR1 (rs12526453, P = 1.0 × 10(-3)) show a nominally significant association with coronary artery calcification with MI/CAD risk alleles increasing the degree of arterial calcification.
