ObjectiveTo investigate the association between TNF-α gene -308G/A polymorphism and the risk of coronary atherosclerotic heart disease (CHD) in Chinese population.MethodsWe searched PubMed, Web of Science, CNKI, WanFang Data and VIP Databases from inception to February 2017, to collect case-control studies about the association between TNF-α gene -308G/A polymorphism and risk of CHD in Chinese population. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed by Stata 12.0 software.ResultsA total of 10 case-control studies were included. The results of meta-analysis showed a significant association between the TNF-α gene -308G/A polymorphism and CHD risk in Chinese population (A vs. G: OR=1.13, 95%CI 1.02 to 1.26, P=0.020; AA vs. GA/GG: OR=1.47, 95%CI 1.02 to 2.12, P=0.038; AA vs. GG: OR=1.50, 95%CI 1.04 to 2.16, P=0.029).ConclusionThe current evidence shows that the TNF-α gene -308G/A polymorphism may be associated with CHD risk in Chinese population and A allele may be a risk factor. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
