摘　　要：Objective:To investigate whether polymorphisms of uridine diphosphoglucuronate-glucuronosyltransferase 1A1(UGT1A1)c.211G>A and glutathione S transferases(GST)gene(GSTT1and GSTM1)are associated with neonatal hyperbilirubinemia.Methods:A case-control study was performed.A multiplex polymerase chain reaction(PCR)was used to detect the GSTT1and GSTM1polymorphisms.Single nucleotide polymorphism of UGT1A1c.211G>A was identified by PCR combined with DNA sequencing.The effects and co-expression of UGT1A1c.211G>A,GSTT1and GSTM1gene polymorphisms on the development of neonatal hyperbilirubinemia were estimated.Results:A allele frequency of c.211G>A polymorphism of UGT1A1gene was 0.186in case group and 0.086in control group,respectively.A allele frequency of the polymorphism of UGT1A1gene in the case group was higher than that of the control group(χ2=5.968,P=0.022).The frequencies of GSTT1and GSTM1in the case group were similar to that of the control groups.Logistic regression analysis showed that UGT1A1c.211G>A variant and UGT1A1+GSTM1 mutation affected neonatal hyperbilirubinemia.Conclusion:UGT1A1c.211G>A gene polymorphism may be one risk factor involved in the development of neonatal hyperbilirubinemia,and GST gene polymorphism may not be associated with the development of neonatal hyperbilirubinemia in our study.The co-expression of UGT1A1c.211G>A and GSTM1polymorphisms may reduce the risk for neonatal hyperbilirubinemia development.Objective：To investigate whether polymorphisms of uridine diphosphoglucuronate-glucuronosyltransferase 1A1（UGT1A1）c.211G〉A and glutathione S transferases（GST）gene（GSTT1and GSTM1）are associated with neonatal hyperbilirubinemia.Methods：A case-control study was performed.A multiplex polymerase chain reaction（PCR）was used to detect the GSTT1and GSTM1polymorphisms.Single nucleotide polymorphism of UGT1A1c.211G〉A was identified by PCR combined with DNA sequencing.The effects and co-expression of UGT1A1c.211G〉A,GSTT1and GSTM1gene polymorphisms on the development of neonatal hyperbilirubinemia were estimated.Results：A allele frequency of c.211G〉A polymorphism of UGT1A1gene was 0.186in case group and 0.086in control group,respectively.A allele frequency of the polymorphism of UGT1A1gene in the case group was higher than that of the control group（χ2=5.968,P=0.022）.The frequencies of GSTT1and GSTM1in the case group were similar to that of the control groups.Logistic regression analysis showed that UGT1A1c.211G〉A variant and UGT1A1＋GSTM1 mutation affected neonatal hyperbilirubinemia.Conclusion：UGT1A1c.211G〉A gene polymorphism may be one risk factor involved in the development of neonatal hyperbilirubinemia,and GST gene polymorphism may not be associated with the development of neonatal hyperbilirubinemia in our study.The co-expression of UGT1A1c.211G〉A and GSTM1polymorphisms may reduce the risk for neonatal hyperbilirubinemia development.
