摘要:

目的 研究AKT1基因多态性与脑膜瘤发病风险的关系。方法 选取2017年10月至2018年1 月在北京天坛医院神经外科手术治疗的脑膜瘤患者 200 例和同期健康体检者 200 例血液标本并提取DNA,应用 SNaPshot 基因分型技术对 AKT1 基因多态位点 rs1130214、rs2494746 和 rs2494752 检测,分析AKT1 基因多态性与脑膜瘤的易感性。结果 AKT1 rs1130214 基因频率在脑膜瘤组和对照组基因型和等位基因频率分布差异无统计学意义(χ2 = 1.499,P = 0.510)。AKT1 基因多态位点 rs2494746 和 rs2494752基因频率在病例组和对照组中基因型和等位基因分布频率差异有统计学意义(rs2494746:χ2 = 9.236,P =0.010;rs2494752:χ2 = 9.044,P = 0.012)。AKT1 位点 rs2494746 在隐性和加性模型中,携带 G 等位基因个体脑膜瘤发病风险均增加(P < 0.05)。rs2494752 在隐性模型下,携带 G 等位基因个体患脑膜瘤风险增加(P < 0.05)。单体型分析结果显示 3 个单体型(CCA、CGA 和 CGG)频率在脑膜瘤组和对照组之间差异均有统计学意义(均 P < 0.05)。结论 AKT1 基因多态位点 rs2494746 和 rs2494752 与脑膜瘤遗传易感性相关,两位点遗传变异均可显著增加脑膜瘤发病风险。

Abstract:

Objective To investigate the association between the single nucleotide polymorphisms ofAKT1 gene and susceptibility to meningioma. Methods Peripheral venous blood samples were obtained from 200patients who had underwent neurosurgical treatment and been histologically diagnosed as meningioma were includedas the case group and 200 healthy controls in Beijing Tiantan Hospital between October 2017 to January 2018. TheAKT1 gene polymorphisms including rs1130214,rs2494746 and rs2494752 were detected by Multiplex SNaPshotmethods. The association of AKT1 gene polymorphisms with susceptibility to meningioma was analyzed. Results There was no significant difference in genotype and allele frequencies of rs1130214 polymorphism of AKT1 genebetween case group and control group(χ2 = 1.499,P = 0.510). The genotype and allele distribution frequencies ofAKT1 rs2494746 and rs2494752 polymorphisms were significantly different between case group and control group(rs2494746:χ2 = 9.236,P = 0.010;rs2494752:χ2 = 9.044,P = 0.012). For the recessive and additive models ofthe rs2494746,individuals with G allele had increased risk of meningiomas(P < 0.05). Haplotype analysisshowed that the frequencies of three haplotypes(CCA、CGA and CGG)were also significantly different betweencase group and control group(all P < 0.05). Conclusion The AKT1 gene polymorphisms rs2494746 andrs2494752 are associated with meningioma susceptibility. Genetic variations of the two polymorphism loci signifi⁃cantly increase the risk of meningioma.
