Uncoupling protein 2(UCP2) is an attractive candidate gene for screening neural tube defects (NTDs) risk. In this study, polymerase chain reaction and agarose gel electrophoresis were used to determine the distribution of the polymorphism in a case group of 140 deliveries with NTDs, and a control group of 251 normal newborns. We found that the frequencies of allele I and genotypes ID + II were higher in the case group than in the control group (P = .167, OR = 1.4, 95% CI, 0.9-2.1; P = .132, OR = 1.44, 95% CI, 0.89-2.33, respectively); and at low maternal educational level, the frequency of ID + II genotypes was significantly higher in the NTD case group (P < .05, OR = 1.7, 95% CI, 1.01-2.79). The result suggested that the polymorphism in UCP2 may be a potential genetic risk factor for NTDs in a high-risk area of China, and the association was influenced by maternal education.
