N2 - Objectives This study was designed to test the hypotheses that single nucleotide polymorphisms ( SNPs), in zinc finger protein 202 ( ZNF202), predict severe atherosclerosis and ischemic heart disease ( IHD). Background ZNF202 is a transcriptional repressor controlling promoter elements in genes involved in vascular maintenance and lipid metabolism. Methods We first determined genotype association for 9 ZNF202 SNPs with severe atherosclerosis ( ankle brachial index >0.7 vs. <= 0.7) in a cross-sectional study of 5,355 individuals from the Danish general population. We then determined genotype association with IHD in 10,431 individuals from the Danish general population, the CCHS ( Copenhagen City Heart Study), including 1,511 incident IHD events during 28 years of follow-up. Results were verified in 2 independent case-control studies including, respectively, 942 and 1,549 cases with IHD and 8,998 controls. Finally, we determined whether g. -660A>G altered transcriptional activity of the ZNF202 promoter in vitro. Results Cross-sectionally, ZNF202 g. -660 GG versus AA homozygosity predicted an odds ratio for severe atherosclerosis of 2.01 ( 95% confidence interval [CI]: 1.34 to 3.01). Prospectively, GG versus AA homozygosity predicted a hazard ratio for IHD of 1.21 ( 95% CI: 1.02 to 1.43). In the 2 case-control studies, the equivalent odds ratios for IHD were 1.29 ( 95% CI: 1.02 to 1.62) and 1.60 ( 95% CI: 1.34 to 1.92), confirming the results from the prospective study. Only 2 other SNPs, which were highly correlated with g. -660A>G, also predicted risk of severe atherosclerosis and IHD. Finally, ZNF202 g. -660G versus g. -660A was associated with a 60% reduction in transcriptional activity in vitro, whereas none of the 2 correlated SNPs were predicted to be functional. Conclusions Homozygosity for a common functional promoter variant in ZNF202 predicts severe atherosclerosis and an increased risk of IHD Udgivelsesdato: 2008/7/29
