2、elting,HRM)法检测骨髓增殖性肿瘤(MPN)患者JAK2V617F基因突变的可行性。随机抽取29份2008年1月至2011年1月确诊为MPN患者的骨髓标本,应用HRM法检测JAK2V617F基因突变情况,并与等位基因特异性聚合酶链反应(AS—PCR)和测序法的检测结果比较分析。结果表明,经HRM法检测,在29份MPN患者骨髓标本中检出突变阳性l1例,突变率为37.9%;与基因测序法比较,结果完全一致,符合率100%。而AS—PCR法与测序法比较,Kappa=0.179,P=0.316,一致性
3、强度较差。结论:HRM方法具有简便、快速、特异性高等优点,可作为临床/(2V617F基因突变的优选方法。关键词高分辨率熔解曲线;JAK2V617F突变;骨髓增殖性肿瘤中图分类号R551.3文献标识码Adoi:10.7534/j.issn.1009—2137.2014.01.023HighResolutionMeltingAnalysisforDetecting0fJAK2V617FMutationinPatientswithMyeloproliferativeNeoplasmsCHENHai.a,Y
