摘要 目的探讨JAK2V617F点突变在骨髓增殖性肿瘤(MPN)患者中的表达及其临床意义。方法应用等位基因特异性聚合酶链反应(AS-PCR)技术进行JAK2V617F点突变的检测,结合临床资料进一步分析。结果87例MPN患者中55例存在JAK2V617F突变(总突变率63.2%)。其中真性红细胞增多症(PV)28例,突变率77.8%(28/36);原发性血小板增多症(ET)17例,突变率51.5%(17/33);原发性骨髓纤维化(PMF)10例,突变率55.6%(10/18);JAK2V617F阳性PV及ET患者初诊时WBC和Hb水平高于JAK2阴性患者(P〈0.05),JAK2V617F阳性PMF患者初诊时WBC和Pu、水平高于JAK2阴性患者(P〈0.05);JAK2V617F阳性MPN患者血栓发生率高于阴性患者(P〈0.05)。结论JAK2V617F点突变在MPN患者中存在较高表达;JAK2V617F阳性MPN患者血细胞计数高于阴性患者,且更易罹患血栓栓塞。
