Abstract

The connexin 37 (Cx37) C1019T gene polymorphism has been suggested to be correlated with increased coronary artery disease (CAD) risk, but research results remain inconsistent. To explore the relationship between the Cx37 C1019T gene polymorphism and CAD in a Chinese population, the current meta-analysis of 6 individual studies involving 1,244 CAD patients and 962 controls was conducted. The pooled odds ratios (ORs) as well as the corresponding 95% confidence intervals (CIs) were estimated using a random- or fixed-effect model. No significant association was found between Cx37 C1019T gene polymorphism and CAD in the Chinese population under the allelic (OR=0.96; 95% CI=0.59‑1.56, P=0.87), recessive (OR=0.77, 95% CI=0.28‑2.08, P=0.60), dominant (OR=0.990, 95% CI=0.773‑1.266, P=0.934), additive (OR=1.000, 95% CI=0.736‑1.359, P=1.000), homozygous (OR=1.062, 95% CI=0.598‑1.887, P=0.836) or heterozygous (OR=1.017, 95% CI=0.802-1.291, P=0.888) genetic models. Cx37 C1019T gene polymorphism was not suggested to be associated with CAD susceptibility in the Chinese population. In conclusion, no association was found between Cx37 C1019T gene polymorphism and CAD in the Chinese population.
