title: Renalase gene polymorphism in patients with hypertension and concomitant coronary heart disease.
abstract: OBJECTIVE
  This study aimed to investigate renalase gene polymorphism in patients with hypertension and concomitant coronary heart disease (CHD) and to evaluate the risk for CHD in hypertensive patients from the view of genetics.
  
  
  METHODS
  NCBI and HapMap genome database were employed to screen the Single nucleotide polymorphisms (SNP). These SNPs were detected in hypertensive and CHD patients (n=791), hypertensive patients (n=802) and healthy controls (n=812), and the genotypes were recorded. Haploview 4.2 software was used to determine the genotypes, allele frequency, haplotypes, linkage disequilibrium and Hardy-Weinberg (HWE) equilibrium, and odds ratio (OR) was calculated with non-conditioned logistic regression analysis.
  
  
  RESULTS
  The frequency of allele A of rs2576178 in patients with hypertensive and CHD was markedly higher than that in hypertensive patients (p=0.001, OR=1.625,95% CI 1.221-2.160). The frequency of allele C of rs2296545 in hypertensive patients was significantly higher than that in healthy controls (P=0.009, OR=1.436, 95% CI 1.095-1.883).
  
  
  CONCLUSIONS
  The allele A of rs2576178 may be a predisposing factor of CHD in hypertensive patients, and hypertensive patients with AA genotype are susceptible to develop CHD. The allele C of rs2296545 may be a predisposing factor of hypertension and patients with CC genotype are susceptible to develop hypertension.
