title: Interaction of ADIPOQ genetic polymorphism with blood pressure and plasma cholesterol level on the risk of coronary artery disease.
abstract: BACKGROUND
  The protective effect of +45T >G polymorphism in the adiponectin gene (ADIPOQ) on coronary artery disease (CAD) has been demonstrated in European populations, so this study investigated the effect of +45T >G polymorphism on the risk of CAD and its interactions with other metabolic risk factors in a Chinese population.
  
  
  RESULTS
  The +45T >G polymorphism (rs2241766) of ADIPOQ was genotyped in 600 patients with angiographically diagnosed CAD and in 718 controls. The G allele at the +45T >G polymorphism was associated with a lower risk of CAD (odds ratio (OR), 0.76; 95% confidence interval (CI), 0.64-0.89; P=0.001). The protective effect of the G allele at +45T >G polymorphism was magnified at blood pressure <140/90 mmHg (OR, 0.65; 95%CI, 0.51-0.82; P=0.0004), but disappeared at blood pressure >or=140/90 mmHg (OR, 0.98; 95%CI, 0.76-1.28; P=0.93), indicating an interaction between +45T >G polymorphism and blood pressure on CAD risk (P=0.02 for interaction). A similar interaction was also observed between plasma cholesterol level and the +45T >G polymorphism.
  
  
  CONCLUSIONS
  An association of ADIPOQ genetic polymorphism with CAD risk is modified by traditional risk factors, such as blood pressure and plasma cholesterol level.
