摘  要:目的探讨肿瘤坏死因子α(TNF-α)编码基因单核苷酸多态性(SNP)位点-308G〉A和-238G〉A基因型与骨髓增生异常综合征(MDS)发生的易感性。方法人组341例原发性MDS患者,对照组为365名与患者无血缘关系的健康志愿者。采用TaqMan探针法对研究人群TNF.cc编码基因SNP位点TNF廿308G〉A、TNF-α-238G〉A进行基因分型。用放射免疫法测定血清TNF-α水平。结果与正常对照组比较,TNF-α-308AA+AG基因型及A等位基因频率在MDS-难治性血细胞减少伴有多系发育异常(RcMD)患者中增加(18%对10%,P=0.015;9%对5%,P=0.021)。MDS患者TNF-α-308及TNF-α-238G〉A基因型及等位基因频率和正常对照组的比较差异均无统计学意义(P值均〉0.05)。MDS患者TNF-α-308G〉A、TNF-α-238G〉A基因型对血清TNF-α水平无明显影响。TNF-α-308G〉AGG基因型与AA+AG基因型MDS患者的血小板计数[58(1~611)×10^9/L对90(7~352)×10^9/L]和骨髓原始细胞比例比较差异有统计学意义(P值分别为0.024、0.019)。结论TNF-α-308G〉A基因多态性与MDS.RCMD患者发生的易感性相关。Objective To investigate the association of single nucleus polymorphisms (SNP) of tumor necrosis factor alpha (TNF-ct) gene (- 308 G〉A and-238 G〉A genotypes) with susceptibility to primary myelodysplastic syndromes (MDS). Methods Two SNPs (TNF-α-308 G〉A,TNF-α-238 G〉A) of TNF-α gene were detected by Taqman probes in 341 MDS patients and 365 unrelated-healthy controls. Results Compared to healthy controls, the frequency of TNF-α-308 AA + AG genotype and A allele increased (18% vs 10%, P=-0.015, 9% vs 5%, P=-0.021, respectively) in refractory cytopenia with multilineage dysplasia (RCMD) patients. There was no correlation of TNF-α-308 G〉A genotype and allele frequency between MDS and controls. No difference in the genotype and allele frequency of TNF-α-238 G〉 A were found between controls and MDS or the subtypes of MDS (P〉0.05).We did not find any linkage between plasma level of TNF-α and TNF-α-308 G〉A or TNF-α-238 G〉A genotype. Statistic differences were observed between platelet count E58( 1-611 ) ×10^9/L vs 90(7-352) × 10^9/L] and bone marrow blasts in MDS patients carrying TNF-α-308 G〉A GG and AA +AG genotype (P=0.024, 0.019, respectively). Conclusion TNF-α-308 G〉A polymorphism was correlated with susceptibility to MDS-RCMD.
