Abstract
The human plasma kallikrein gene (KLKB1) encodes plasma kallikrein, a serine protease that catalyzes the release of kinins and other vasoactive peptides and may be involved in the pathogenesis of hypertension. In this study, we performed a haplotype-based study to assess the effect of common genetic variation in the KLKB1 gene on the risk of essential hypertension. Eight common single nucleotide polymorphisms (SNPs) were selected from the HapMap database and used to determine the pattern of linkage disequilibrium (LD) and haplotype structure within the KLKB1 gene. Four tag SNPs were then identified with over 85% power to predict both common haplotypes and remaining common SNPs, and genotyped in 1,317 cases with essential hypertension and 1,269 healthy controls. Single SNP analyses indicated that SNPs rs2304595 and rs4253325 were significantly associated with hypertension, adjusted for covariates. Compared with the most common Hap2 CAGC, Hap1 AGAC and Hap3 CGAC, which carry the susceptible rs2304595 G allele and rs4253325 A allele, were found to significantly increase the risk of essential hypertension with adjusted odds ratios equal to 1.37 and 1.17, respectively (P < 0.0001 and 0.028). A strongly significant interaction with gene-drinking was also observed. Among drinkers, the adjusted OR for Hap1 relative to Hap2 was increased to 2.50 (95% CI, 2.40 to 2.61; P < 0.0001). This was the first study to perform association analysis of the KLKB1 gene with essential hypertension. Our findings suggested that common genetic variation in the KLKB1 gene might contribute to the risk of hypertension in the northern Han Chinese population.
