MTHFRC677T、MTHFRA1298C和MTRRA66G基因的多态性与急性髓系白血病的相关性分析

摘要

Objective To investigate the relationship of the MTHFRC677T,MTHFRA1298C,and MTRRA66G gene polymorphisms with acute myelocytic leukemia (AML).Methods Mononuclear cells were collected from 63 patients diagnosed with AML,and 60 healthy,non-AML control-group patients.DNA extracted from each sample was screened for the MTHFRC677T,MTHFRA1298C,and MTRRA66G polymorphisms.Results No significant difference was observed in the distribution of the MTHFRC677T,MTHFRA1298C,and/or MTRRA66G polymorphisms between the two patient groups.In contrast,the MTRR G allele was observed to occur 1.935 times more frequently than the MTRR an allele (x2 =4.708,P ＜ 0.05,95％ CI:1.061-3.530).No significant difference was observed in the distribution of a combination of the three gene polymorphisms (MTHFRC677T,MTHFRA1298C,and MTRRA66G)between the AML and the control group.Conclusion The results of the present study suggest that the MTHFRC677T,MTHFRA1298C,and MTRRA66G polymorphisms are not associated with AML.%目的 探讨MTHFRC677T、MTHFRA 1298C以及MTRRA 66G的基因多态性与急性髓系白血病(AML)的相关性.方法 应用实时PCR方法检测并分析63例AML患者以及60例正常对照者MTHFRC677T、MTHFRA1298C以及MTRRA66G的多态性.结果 对2组患者进行MTHFRC677T、MTHFRA1298C以及MTRRA66G基因多态性分析,得出3个位点的等位基因多态性与AML不存在必然联系.MTHFRC677T、MTHFRA 1298C以及MTRRA66G单倍型基因分析结果表明,MTRR66位G等位基因在对照组中有所增多,与MTRR66位A等位基因相比增加了1.935倍(95％ CI:1.061～3.530,x2=4.708,P＜ 0.05).将2组人群的基因型进行3个位点的整合,突变状况分析结果显示其与AML也无必然联系.结论 MTHFRC677T、MTHFRA1298C和MTRRA66G基因多态性与AML无明显相关性.
