title: Haplotype analysis of PPARγ C681G and intron CT variants. Positive association with essential hypertension.
abstract: BACKGROUND
  There is strong evidence suggesting an association between the peroxisome-activated receptor γ (PPARγ) gene and multimetabolic disorders. The association of PPARγ genetic variants with essential hypertension (EH) has not yet been investigated. The aim of this study was to investigate the association between the PPARγ gene (C681G and intron CT) and EH, examining the polymorphism and haplotype in a Han Chinese population.
  
  
  METHODS
  Participants were recruited within the framework of the PMMJS cohort population survey in an urban community of Jiangsu Province, China. Two single-nucleotide polymorphisms (SNPs) previously reported to be associated with multimetabolic disorders and the reasonable coverage of the PPARγ gene region were analyzed with TaqMan SNP genotyping assays.
  
  
  RESULTS
  C681G and intron CT were significantly associated with an increased risk of EH both in the codominant model and the dominant model after adjusting for potential nongenetic risk factors. Analysis of the haplotype association revealed that the risk of EH was significantly increased among individuals carrying the GC (odds ratio, 95 % CI: 1.60, 1.21-2.11), CT (1.45, 1.03-2.11), and GT haplotypes (1.95, 1.17-3.23) compared with those carrying the CC haplotype.
  
  
  CONCLUSIONS
  The polymorphisms of C681G and intron CT were significantly associated with the risk of EH, and the GC, CT, and GT haplotypes established by C681G and intron CT are likely to be genetic markers of EH in the Han Chinese population.
