智商(IQ)是表征人类认知能力的最常用的表型。最近对人类智力的研究进展发现了许多新的易感基因。然而,智商得分所涉及的遗传机制以及智商得分与精神障碍风险之间的关系却鲜有人关注。为了解决智商得分的遗传复杂性,我们开发了IQdb(http://IQdb.cbi.pku.edu.cn),),这是一个公开可用的数据库,用于探索与智商相关的人类基因。总而言之,我们从文献中收集了158个实验验证基因作为IQdb的核心数据集。此外,已从文献中筛选出46个与智商得分相关的基因组区域。基于核心数据集和46个已确认的连锁基因组区域,利用蛋白质-蛋白质相互作用的数据扩展了6932个潜在的智商相关基因。系统的基因排序方法被应用于所有收集和扩展的基因,以代表所有7090个基因在IQdb中的相对重要性。我们进一步的系统通路分析表明,智商相关基因在多个信号事件中显著丰富,特别是与认知系统相关的信号事件。在核心数据集中的158个基因中,有81个与各种精神病和精神障碍有关。这一全面的基因资源说明了IQdb对我们理解人类智力的重要性,并突出了IQdb在阐明IQ相关基因的功能以及社区某些精神障碍认知相关通路之间的串扰机制方面的作用。数据库地址:http://IQdb.cbi.pku.edu.cn.
Intelligence quotient (IQ) is the most widely used phenotype to characterize human cognitive abilities. Recent advances in studies on human intelligence have identified many new susceptibility genes. However, the genetic mechanisms involved in IQ score and the relationship between IQ score and the risk of mental disorders have won little attention. To address the genetic complexity of IQ score, we have developed IQdb (http://IQdb.cbi.pku.edu.cn), a publicly available database for exploring IQ-associated human genes. In total, we collected 158 experimental verified genes from literature as a core dataset in IQdb. In addition, 46 genomic regions related to IQ score have been curated from literature. Based on the core dataset and 46 confirmed linked genomic regions, more than 6932 potential IQ-related genes are expanded using data of protein–protein interactions. A systematic gene ranking approach was applied to all the collected and expanded genes to represent the relative importance of all the 7090 genes in IQdb. Our further systematic pathway analysis reveals that IQ-associated genes are significantly enriched in multiple signal events, especially related to cognitive systems. Of the 158 genes in the core dataset, 81 are involved in various psychotic and mental disorders. This comprehensive gene resource illustrates the importance of IQdb to our understanding on human intelligence, and highlights the utility of IQdb for elucidating the functions of IQ-associated genes and the cross-talk mechanisms among cognition-related pathways in some mental disorders for community.
