BMC MED:影响“渐冻症”患者生存的遗传因素有哪些?

2022-07-10 MedSci原创 MedSci原创

研究总结和对比了ALS预后遗传因素的证据,将有助于了解ALS的发病机制,指导临床试验和药物开发。

肌萎缩性脊髓侧索硬化症(ALS)患者的存活时间差异很大,而对ALS存活的遗传因素的研究并不充分。目前还缺乏一个全面的研究来阐明遗传因素在ALS生存中的作用。为此,来自我国华西医学院的神经病学学者开展了相关研究,结果发表在BMC Medicine杂志上。

研究人员从PubMed、EMBASE和Cochrane图书馆中系统地搜索并获得从开始到2021年10月27日的已发表研究。对ALS的致病/风险基因进行了网络荟萃分析,对其他遗传修饰因素进行了系统回顾和配对荟萃分析。

结果共确定了29764篇潜在的相关参考文献,根据预先确定的标准,有71篇论文符合分析条件,包括9个ALS致病/风险基因的网络元分析中的35篇文章,4个遗传修饰因子的配对元分析中的17篇文章,以及系统回顾中描述的19篇文章。包括ATXN2(HR=3.6)、C9orf72(HR=1.6)和FUS(HR=1.8)在内的三个基因的变异与ALS的短生存期有关,但SOD1、TARDBP、TBK1、NEK1、UBQLN2和CCNF没有发现这种关联。此外,UNC13A rs12608932 CC基因型和ZNF521B rs2275294 C等位基因也会导致ALS生存期缩短;然而,APOE ε4等位基因和KIFAP3 rs1541160没有发现对ALS生存期有任何影响。

综上,研究总结和对比了ALS预后遗传因素的证据,将有助于了解ALS的发病机制,指导临床试验和药物开发。
