This study was conducted using TagSNPs to systematically explore the relationship between polymorphisms and the occurrence, clinical characterization, and prognosis of acute myeloid leukemia (AML). A total of 569 unrelated AML patients and 410 healthy individuals from West China were recruited, and TagSNPs were genotyped using iMLDR (improved multiplex ligation detection reaction). It was found that the association of polymorphisms with AML was most significant in acute promyelocytic leukemia (APL), and exclusively in males, the mutant alleles of rs6415872, rs2393726, rs7073837, rs10821936, and rs7089424 were found to increase the risk of developing APL in men, the odds ratio (OR) were 1.36, 1.74, 1.45, 1.53, and 1.56 (all < 0.05), respectively. Haplotype analysis revealed that haplotype [AACCG] increased the risk of male APL with an OR of 1.53 (95% confidence interval: 1.10-2.14, = 0.012). Besides, there was a strong positive additive interaction between rs6415872 and rs10821936, rs7089424, respectively, and cases attributed to the interaction of rs6415872, rs10821936, and rs7089424 accounted for 100%. Furthermore, single nucleotide polymorphisms were found associated with clinical features of AML, and rs6415872 was shown to be an independent prognosis factor in APL patients. Besides, dual luciferase report assay showed that rs6415872 may affect the binding activity of with . polymorphisms contribute to male APL risk, clinical feature, and prognosis, suggesting the importance of in AML pathogenesis and development, and the gender and subtype preference may prompt some specific mechanisms of . Besides, polymorphisms might be a potential prognosis biomarker.
这项研究使用 TagSNP 来系统地探索多态性与急性髓细胞白血病 (AML) 的发生、临床特征和预后之间的关系。共招募了来自华西的 569 名无关 AML 患者和 410 名健康个体,使用 iMLDR(改良多重连接检测反应)对 TagSNP 进行基因分型。结果发现,多态性与 AML 的关联在急性早幼粒细胞白血病 (APL) 中最为显著,且仅在男性中,rs6415872、rs2393726、rs7073837、rs10821936 和 rs7089424 的突变等位基因被发现增加了男性发生 APL 的风险,优势比 (OR) 分别为 1.36、1.74、1.45、1.53 和 1.56(均 < 0.05)。单体型分析显示,单体型 [AACCG] 增加了男性 APL 的风险,OR 为 1.53(95%置信区间:1.10-2.14, = 0.012)。此外,rs6415872 与 rs10821936、rs7089424 之间存在强烈的正相加交互作用,归因于 rs6415872、rs10821936 和 rs7089424 相互作用的病例占 100%。此外,单核苷酸多态性与 AML 的临床特征相关,rs6415872 被证明是 APL 患者的独立预后因素。此外,双荧光素酶报告试验表明,rs6415872 可能影响 与 的结合活性。 多态性有助于男性 APL 风险、临床特征和预后,提示 在 AML 发病机制和发展中的重要性,以及性别和亚型偏好可能提示某些特定的机制。此外, 多态性可能是一个潜在的预后生物标志物。
