Objective Evidence from animal models and human studies suggests that CYP2J2 plays a mechanistic role in the development of hypertension. The present study aims to investigate the potential genetic contribution of the CYP2J2 gene to the etiology of essential hypertension (EH) and individual blood pressure. Methods We selected eight polymorphisms in/or around the CYP2J2 gene and performed a case-control association study involving 841 Han Chinese subjects, including 415 unrelated hypertensives and 426 age-, gender- and area-matched normotensives. Results Three functionally identified variants (CYP2J2 *2, *7 and CYP2J2 *8) and SNP rs11572182 represented rare polymorphisms in Han Chinese. However, the difference in rs1155002 genotype distribution between hypertensive and healthy subjects was close to significance (P = 0.06) in the whole sample. Interestingly, significant evidence for an association with rs1155002 was found in females when stratified by gender. In females, the TT homozygote of rs1155002 seems to be a risk factor for hypertension (p = 0.014). In addition, ANOVA analysis suggested TT carriers had significantly higher systolic blood pressure (p = 0.016). The genotype frequencies for rs10493270, rs1180273 and rs1324491 revealed no statistically significant differences. Likewise, four-marker haplotype frequencies showed no significant differences between cases and controls. Conclusion Our data provide strong evidence that the CYP2J2 gene is a susceptibility factor for essential hypertension, especially in females, and influences individual systolic blood pressure in the Chinese Han population.
