title: Association between renin-angiotensin-aldosterone system-related genes and blood pressure in a Korean population.
abstract: AIMS. Blood pressure control is influenced by various genetic and environmental factors, and genetic susceptibility is important in the development of essential hypertension. Because the renin-angiotensin-aldosterone system (RAAS) has a key role in vasoconstriction, vasodilation, and sodium and electrolyte balance, it is central in blood pressure control and so is an appropriate target in hypertension treatments. The present study assessed the association of RAAS-related genes with blood pressure and hypertension in a Korean population. Single nucleotide polymorphisms (SNPs, n = 114) in nine RAAS-related genes (AGT, REN, ACE, ACE2, AGTR1, CYP11B2, NR3C2, MAS1, and CMA1) were assessed for their correlation with blood pressure and hypertension using genotype data of 8842 individuals from the Korea Association Resource subject pool. MAJOR FINDINGS. Linear regression analysis revealed a statistically significant association with blood pressure of 10 SNPs in six genes (ACE, ACE2, CYP11B2, NR3C2, MAS1, and CMA1). An additional hypertension case-control study identified 10 SNPs in NR3C2 and ACE that were linked to hypertension. PRINCIPAL CONCLUSION. Three SNPs (rs11737660, rs6810951, and rs10519963) in NR3C2 correlate with both blood pressure and hypertension. Genetic polymorphisms in RAAS-related genes appear to be associated with hypertension in a Korean population.
