STATS基因多态性与哮喘的相关性研究

摘要

Objective To investigate the correlation rs2272087 polymorphism of STATS gene and asthma.Methods The polymerase chain reaction PCR- SBT technique was used to determine rs2272087 polymorphism in asthma and control group.Results The genotype of AA,AG and GG of rs2272087 were 0.600,0.412 and 0.167 in asthma group,and 0.430,0.200,0.367 in control group,respectively.The frequency of allele A and G was 0.903 and 0.344 in asthma group,and 0.656,0.970 in control group,respectively.There was significant difference in two groups(x2 =9.40,P ＜0.01 ;x2 =11.58,P ＜0.01 ).Conclusions The rs2272087 polymorphism of STAT5 gene may be an important candidate gene for asthma.%目的 探讨信号转导子和转录激活子5( Signal Transducer and Activators of Transcription 5,STAT5)基因rs2272087位点多态性与哮喘易感性的关系.方法 采用聚合酶链反应-直接测序法(polymerase chain reaction sequencing-based typing,PCR-SBT)技术检测哮喘组与对照组STAT5基因rs2272087位点多态性.结果 rs2272087位点基因型频率AA、AG和GG在哮喘组分别为0.600、0.412和0.167,在对照组分别为0.430、0.200和0.367；等位基因A、G频率在哮喘组分别为0.903和0.390,在对照组分别为0.656和0.097；两组的基因型频率及等位基因频率比较差异有统计学意义(x2 =9.40,P＜0.01；x2 =11.58,P＜0.01).结论 STAT5基因rs2272087位点多态性可能是影响哮喘的重要候选基因.
