We genotyped 2277 individuals, age 24 to 39 years, from the Cardiovascular Risk in Young Finns Study with CIMT and FMD measurements and 1295 individuals, age 46 to 76 years, from the Health 2000 Survey with CIMT for rs1333049, the chromosome 9p21 variant showing the strongest association with CAD.
The meta-analysis of the rs1333049 SNP in 12,0</span>04 cases and 28,949 controls increased the overall level of evidence for association with CAD to P=6.04x10(-10) (odds ratio, 1.24; 95% confidence interval, 1.20 to 1.29).
Higher FRS and PWV and the presence of rs2943634 risk allele were independent predictors of CAD (Nagelkerke R(2) 0·252, P < 0·001), while higher FRS and the presence of rs1333049 risk allele were independent predictors of multivessel CAD (Nagelkerke R(2) 0·190, P < 0·001).
We examined the prognostic values of the rs9508025 and rs1333049 variants that were found to be associated with coronary artery disease (CAD) risk in a previous Korean genome-wide association study.
Further subgroup analyses showed that rs1333040, rs1333049 and rs2383207 polymorphisms were significantly correlated with the risk of CAD in East Asians, rs2383206 and rs10757274 polymorphisms were significantly correlated with the risk of CAD in West Asians, while rs2383206, rs10757274 and rs10757278 polymorphisms were significantly correlated with the risk of CAD in Caucasians.
Recent genetic studies identified the rs1333049 variant on chromosome 9p21 as a major susceptibility locus for coronary artery disease and myocardial infarction (MI).
