摘要: 目的: 检测白血病Flt3基因近膜区突变,探讨与白血病发生、发展的关系。方法:采用PCR、PCR-SSCP和DNA测序方法,对60例白血病患者骨髓标本Flt3基因外显子14、15进行检测,以20名健康志愿者骨髓标本作为对照。结果:在60例白血病患者中,发现8例Flt3-ITD突变,3例Flt3-L576P点突变,其中1例合并有Flt3基因内含子14缺失突变。结论:白血病Flt3-L567P点突变是近膜区新发现的点突变,可能与白血病的发生、发展相关。

Abstract: OBJECTIVE: To identify the relationship between the pathogenesis of leukemia and Flt3 gene by detecting the mutations in juxtamembrane domain coded by Flt3. METHODS:We tested exons14,15 of Flt3 gene using PCR,PCR-SSCP and gene sequence in 60 leukeamia patients’ bone marrow samples. RESULTS:8 Flt3-ITD mutations,another 3 Flt3-L576P point mutations were found in juxtamembrane domain in 60 patients,including 1 patient with a deletion of intron 14. CONCLUSION:Flt3-L576P is a new point mutation site,which might be associated with the pathogenesis and development of leukemia.
