主要组织相容性复合体Ⅱ类反式激活因子基因编码区单核苷酸多态性与慢性乙型肝炎病毒感染的转归
The relationship between single nucleotide polymorphism in the coding region of class Ⅱ transactivator gene and outcomes of chronic hepatitis B virus infection
摘要：目的 探讨主要组织相容性复合体(MHC)Ⅱ类反式激活因子(CⅡTA)编码区两个非同义单个核苷酸多态性(SNP)位点C19170G、C30799G的多态性与慢性HBV感染不同临床表型的关系.方法 在627例不同临床表型的慢性HBV感染人群与101名健康献血员中,用序列特异性引物-聚合酶链反应(PCR-SSP)的方法对CⅡTA编码区两个非同义SNP位点C19170G、C30799G进行基因分型;X2检验判断上述位点的基因型分布是否符合Hardy-Weinberg平衡;列联表X2检验检测两组间的差异;非条件Logistic回归进行分析.结果 CⅡTA基因编码区19170位点G等位基因和GG+GC基因型在肝硬化人群中的频率显著高于其在非进展性肝病人群中的频率(X27.128,P=0.008;X26.404,P=0.011),且各基因型频率在肝硬化与非进展性肝病两组人群间存在显著差异(OR:0.742,95%CI:0.552～0.998,P=0.048),其两者间的差异主要存在于G基因显性模式下(OR:0.581,95%CI:0.353～0.954,P=0.032);30799位点C等位基因和CC基因型在肝细胞癌人群中的频率显著高于其在肝硬化人群中的频率(X24.861,P=0.027;X24.993,P=0.025).且各基因型频率在肝硬化与肝细胞癌两组人群间存在显著差异(OR:0.557,95%CI:0.334～0.930,P=0.025),其两者间的差异主要存在于C基因隐性模式下(OR:0.491,95%CI:0.269～0.898,P=0.021).结论 在慢性HBV感染者中,C19170G位点多态性与肝硬化的形成密切相关,携带G等位基因者易发展为肝硬化;C30799G位点多态性与肝细胞癌的发生密切相关,携带CC基因型者易发展为肝细胞癌.更多abstracts：Objective To investigate the relationship between the non-homonymy single nucleotide polymorphism(SNP)of C19170G,C30799G in the coding area of class Ⅱ transaetivator(CII TA)and the different clinical phenotypes of chronic hepatitis B virus(HBV)infection.Methods Six hundred and twenty-seven patients with chronic HBV infection and 101 healthy blood donors were enrolled in this study.Genotyping of C19170G,C30799G in C Ⅱ TA gene coding region were done by sequence-specific primer polymerase chain reaction(PCR-SSP).Hardy-Weinberg balance of the genotypes was analyzed using chi-square test.Differences between two sets were tested by contingency table chi-square test and unconditional Logistic regression was performed. Results The frequencies of G allele and GG+GC genetypes at 19170 site were significantly higher in patients with liver cirrhosis than those with non-progressive liver diseases(X2=7.128,P=0.008;X2=6.404,P=0.011,respectively).There were significantly differences of the allele frequencies between patients with liver cirrhosis and non-progressive liver diseases(OR:0.742,95%CI:0.552～0.998,P=0.048),and the main differences were observed in G dominant model(OR:0.581,95% CI:0.353～0.954,P=0.032).The frequencies of C allele and CC genotype at 30799 site were significantly higher in patients with hepatocellular carcinoma than those in patients with liver cirrhosis(X2=4.861,P=0.027;X2=4.993,P=0.025).There were significant differences of the genotype frequencies at 30799 site between patients with liver cirrhosis and hepatocellular carcinoma(OR:0.557,95% CI:0.334～0.930,P=0.025),and the differences were mainly observed in C recessive model(OR:0.491,95% CI:0.269～0.898,P=0.021).Conclusions The polymorphisms at 19170 site are associated with liver cirrhosis in chronic HBV infection,and the G allele carriers are prone to progress into liver cirrhosis.The polymorphisms at 30799 site are associated with hepatocellular carcinoma in chronic HBV infection,and CC genotype carriers are prone to progress into hepatocellular carcinoma.More
