DNMT3A Gene Mutations In Acute Myeloid Leukemia

Abstract

目的:了解DNMT3A基因在急性髓系白血病(Acutemyeloidleukemia,AML)患者中的突变比例和类型,分析DNMT3A基因突变患者的临床特征和突变在AML种的预后价值,分析该突变在疾病进展中的变化情况。 方法:抽取101例髓系白血病患者的骨髓或外周血,提取RNA逆转录成cDNA,并设计两对引物用于扩增DNMT3A基因,电泳验证产物条带后进行直接测序。提取所有患者的全基因组DNA进行毛细管电泳,检测NPM1和FLT3-ITD两种基因的突变情况。同时检测其它相关危险因素,如外周血白细胞数、免疫表型、染色体核型,并进行统计学分析。 结果:共检测出14例(13.9%)突变患者,其中...Objective: To detect the frequency and forms of DNMT3A gene mutations in patients with acute myeloid leukemia(AML),and to investigate the relationship between DNMT3A mutations and clinical feature of AML.Monitoring mutations in two cases during the clinical course. Methods: DNA and RNA was Extracted from bone marrow or peripheral blood samples.PCR followed by reverse transcriptase was used to amp...学位:医学硕士院系专业:医学院临床医学系_内科学学号:2452009115293
