Effect of the genetic variants of heme oxygenase-1 gene on blood pressure level in hypertensive pailents / 中国综合临床

ABSTRACT

Objective To assess the relationship between the polymorphisms of heme oxygenase-1 gene and blood pressure level.Methods With the whole-gene based tagging SNP approach,3 tag SNPs of heme oxygenase-1 gene were selected for study.These tag SNPs were genotyped in 503 essential hypertension cases Blood pressure lev-els among different genotypes of each SNP were compared with ANOVA.The haplo.stats program wa8 employed to test haplotype frequency with blood pressure level.Results Subjects with rs2071749 A allele had the lower blood pressure levels than subjects with GG genotypes(SBP159.5 mm Hg vs.168.5 mm Hg and DBP97.6 mm Hg vs.101.3 mm Hg respectively.P<0.05).In the haplotype analyses.Haplotype T-T-A which carried the rs2071749 A allele was found significantly associated with SBP and DBP after adjustment for age,gender,body mass index.8n10k.illg and drinking·Conclusion The genetic variants of heine oxygenase.1 gene misht be associated with blood pres-sure levels.
