ObjectiveTo systematically evaluate the association between 936C/T polymorphism in vascular endothelial growth factor (VEGF) gene and the risk of preeclampsia (PE). MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2014), CBM, CNKI, VIP, and WanFang Data were searched up to November 2014, to collect case-control studies of the association between 936C/T polymorphism in VEGF gene and the risk of PE. Two reveiwers independently screened studies according to the inclusion and exclusion criteria, extracted data, and assessed the risk of bias of included studies. And then, meta-analysis was conducted using RevMan 5.3 software. ResultsA total of nine case-control studies involving 904 PE patients and 1 113 controls were included. The results of meta-analysis showed that, significant association was found between VEGF gene 936C/T polymorphism and the risk of PE in the total analysis (T vs. C:OR=1.61, 95%CI 1.17 to 2.22, P=0.003; TT vs. CC:OR=2.65, 95%CI 1.37 to 5.11, P=0.004; CT vs. CC:OR=1.55, 95%CI 1.09 to 2.22, P=0.02; TT+CT vs. CC:OR=1.68, 95%CI 1.15 to 2.45, P=0.007; TT vs. CT+CC:OR=2.19, 95%CI 1.31 to 3.68, P=0.003). In the subgroup analysis, significant association of the polymorphism was found in Asians but not in Caucasians. ConclusionVEGF gene 936C/T polymorphism may be associated with PE risk in Asians. Due to limited quantity and quality of the included studies, the conclusion should be assessed in further studies.
