INT J LAB HEMATOL:联合allele-specific PCR和淬火探测方法对MYD88基因突变进行检测

2017-04-18 MedSci MedSci原创

在Waldenstörm的巨球蛋白血症和淋巴瘤患者中发现MYD88错义突变c.794T> C,p.Leu265Pro。目前使用直接测序,等位基因特异性PCR(AS-PCR),PCR限制性片段长度多态性(PCR-RFLP)和高分辨率融合分析(HRM)检测突变。但是,这些方法有的耗时,有的检测灵敏度低。在此,研究人员开发了一种基于淬灭探针(QP)技术和AS-PCR的新型高灵敏度和快速的检测方法。

近日,国际杂志INT J LAB HEMATOL上在线发表一篇关于联合allele-specific PCR和淬火探测方法对MYD88基因突变进行检测的研究。

Waldenstörm的巨球蛋白血症和淋巴瘤患者中发现MYD88错义突变c.794T> Cp.Leu265Pro。目前使用直接测序,等位基因特异性PCRAS-PCR),PCR限制性片段长度多态性(PCR-RFLP)和高分辨率融合分析(HRM)检测突变。但是,这些方法有的耗时,有的检测灵敏度低。在此,研究人员开发了一种基于淬灭探针(QP)技术和AS-PCR的新型高灵敏度和快速的检测方法。

通过AS-PCRPCR-RFLPHRMQP分析了MYD88突变杂合的淋巴瘤细胞系,两个野生型细胞系和来自Waldenstörm的巨球蛋白血症患者的两个样品,并使用突变体和野生型DNA测定监测灵敏性。

研究结果显示,对于携带突变携带杂合子样品,来自野生型和突变等位基因在QP方法检测中显示出了W型融合谱曲线。与其他方法相似,QP分析在2 h内进行检出限为5%。 然而,AS-PCRQPAS-QP)的联合检测方法将突变等位基因灵敏度提高到了0.62%。

研究表明,与AS-PCR相比,AS-QP分析是快速的检测方法,并且最小程度地提高了检测灵敏度。
