Association of Zinc Finger, C3HC-Type Containing 1 (ZC3HC1) rs11556924 Genetic Variant With Hypertension in a Finnish Population, the TAMRISK Study.

ABSTRACT: In a recent genome-wide association study, the zinc finger, C3HC-type containing 1 (ZC3HC1) polymorphism was strongly associated with coronary artery disease (CAD) by an unknown mechanism. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is related with CAD through low-density lipoprotein (LDL) metabolism. The association of both of the above genetic variants with hypertension was studied in a Finnish 50-year-old cohort.A total of 325 hypertensive cases and 444 nonhypertensive controls were obtained from the Tampere adult population cardiovascular risk study. Samples were genotyped for ZC3HC1 rs11556924 and PCSK9 rs11206510 polymorphisms using Competitive Allele Specific PCR technique. A subpopulation that had available follow-up data from ages of 40, 45, and 50 years was also analyzed.ZC3HC1 rs11556924 (C?>?T) genotype CC was associated with hypertension compared with the T-allele carriers (P?=?0.013). PCSK9 rs11206510 (T?>?C) genotype was not associated with hypertension. Its major TT-genotype was associated with higher total cholesterol (P?=?0.044) and LDL (P?=?0.029) compared with the C-allele.We report for the first time that ZC3HC1 rs11556924 was associated with essential hypertension in 50-year-old patients. Although PCSK9 rs11206510 was not associated with hypertension, our study confirms its association with serum cholesterol levels.

Project description:Increased inducible nitric oxide synthase (iNOS) activity and expression has been associated with hypertension, but less is known whether the 2 known functional polymorphic sites in the iNOS gene (g.-1026 C/A (rs2779249), g.2087 G/A (rs2297518)) affect susceptibility to hypertension. The objective of this study was to investigate the association between the genetic variants of iNOS and diagnosed hypertension in a Finnish cohort.This study included 320 hypertensive cases and 439 healthy controls. All participants were 50-year-old men and women and the data were collected from the Tampere adult population cardiovascular risk study (TAMRISK). DNA was extracted from buccal swabs and iNOS single nucleotide polymorphisms (SNPs) were analyzed using KASP genotyping PCR. Data analysis was done by logistic regression.At the age of 50 years, the SNP rs2779249 (C/A) associated significantly with hypertension (P?=?0.009); specifically, subjects carrying the A-allele had higher risk of hypertension compared to those carrying the CC genotype (OR?=?1.47; CI?=?1.08-2.01; P?=?0.015). In addition, a 15-year follow-up period (35, 40, and 45 years) of the same individuals showed that carriers of the A-allele had more often hypertension in all of the studied age-groups. The highest risk for developing hypertension was obtained among 35-year-old subjects (odds ratio [OR] 3.83; confidence interval [CI]?=?1.20-12.27; P?=?0.024). Those carrying variant A had also significantly higher readings of both systolic (P?=?0.047) and diastolic (P?=?0.048) blood pressure during the follow-up. No significant associations between rs2297518 (G/A) variants alone and hypertension were found. However, haplotype analysis of rs2779249 and rs2297518 revealed that individuals having haplotype H3 which combines both A alleles (CA-GA, 19.7% of individuals) was more commonly found in the hypertensive group than in the normotensive group (OR?=?2.01; CI?=?1.29-3.12; P?=?0.002).In conclusion, there was a significant association between iNOS genetic variant (rs2779249) and hypertension in the genetically homogenous Finnish population. Those who carried the rare A-allele of the gene had higher risk for hypertension already at the age of 35 years.
