Replication of genome-wide significant association SNPs in independent populations is an essential approach for identifying gene–disease relationships. Therefore, we sought to investigate the top 21 SNPs (rs10507454, rs11897156, rs11897991, rs12325203, rs12541835, rs13395322, rs1525035, rs16936892, rs17010027, rs17045859, rs17136827, rs1866525, rs2045590, rs4547758, rs4655688, rs7107438, rs761353, rs8127139, rs9312305, rs9407874 and rs9865108) from a genome-wide association study of essential hypertension in Mongolians. This was a community-based case-control study involving 428 hypertensives and 638 normotensives from Kerqinzuoyihou Banner,Tongliao, Inner Mongolian Autonomous Region, China. Genotyping was conducted with Sequenom MassArray (®) SNP detection technology. Overall, there were no significant differences in the genotype distributions and allele frequencies between the cases and controls. There was a significant difference between the allele frequencies at locus rs17010027 in cases (high systolic blood pressure) and controls in female (p = .036). There were significant differences in the distribution of genotypes and the allele frequencies at locus rs10507454 between cases (high diastolic blood pressure) and controls (p = .019 and p = .022, respectively) especially in male (p = .009 and p = .011, respectively). rs17010027 is associated with high systolic blood pressure in female, and rs10507454 is associated with high diastolic blood pressure especially in male of this Mongolian population.
