摘要: 目的 通过对颅内动脉瘤病人和对照组的比较研究,探讨Ⅲ型胶原蛋白基因α1(COL3A1基因)与颅内动脉瘤之间的相关关系。方法 抽取病例组和对照组的外周血,并提取基因组DNA,选择目的基因片断,设计聚合酶链反应(PCR)所需引物并合成,应用PCR反应扩增感兴趣的目的片断,经琼脂糖电泳验证后进行测序反应,比较病例组和对照组之间COL3A1基因多态性出现频率的差异。结果 通过统计分析发现,2组研究对象的COL3A1基因功能性SNP-rs1800255基因型之间,差异具有统计学意义(χ2=4.94,P<0.05)。结论 COL3A1基因的功能性SNP-rs1800255与国内散发颅内动脉瘤病人之间存在明显相关,COL3A1基因是国内散发颅内动脉瘤病人的易感基因之一。

Abstract: Objective To investigate the possible relationship between the Ⅲ collagen α1(COL3A1) gene and the Chinese sporadic intracranial aneurysms. Methods Obtain the venous blood of the two group cases and extract genomic DNA. After the primer design and synthesis, the polymerase chain reaction(PCR) was performed and the PCR products were examined via the 1% agarose gel electrophoresis, and finally the products were sequenced to investigate the frequency discrepancy of certain single nucleotide polymorphism of COL3A1. Results After statistic analysis, the difference of genotype frequency between the intracranial aneurysms and control group was statistically significant, the P value of which is lower than 0.05. Conclusion There is significant relationship between the functional SNP of COL3A1 gene and sporadic intracranial aneurysms patients and COL3A1 gene would be one of the candidate genes of the Chinese sporadic intracranial aneurysms.
