Hypertension is a complex disease that is caused by the interaction of multiple genetic and environmental risk factors, affecting 30% adult in industrialized countries. The identification of genetic factors that impact one's predisposition to hypertension and its progression is an ongoing challenge. A genome-wide association study of African-Americans, who have one of the highest rates of hypertension in the world,was reported. We replicated the GWAS results in 8842 unrelated Koreans. Fifteen of the 30 reported SNPs were analyzed for their association with blood pressure and hypertension. Linear regression was used to analyze blood pressure as a quantitative trait in 7551 subjects, and a case-control study was performed using 1968 hypertensive cases and 4452 normotensive controls by logistic regression analysis. The quantitative trait study demonstrated a moderate association of 2 SNPs, rs9301196 (p=4.9×10^(-3) for diastolic blood pressure) and rs2823756 (p=0.04 for systolic blood pressure), which were also associated with hypertension (p=0.042 and p=6.3×10^(-3), respectively). Further, 3 SNPs were associated with hypertension (p=0.042 for rs7902529,p=0.027 for rs10135446, and p=0.01 for rs4613079) but not with blood pressure. Based on the moderate association signals and the low proportion of positive signals, this cross validation between African-Americans and Asians suggests that association studies of blood pressure traits require a larger number of subjects and a more refined design.
