在全基因组关联时代之前,候选基因研究是精神分裂症遗传学的主要方法。在这篇特邀综述中,我们考虑了25个精神分裂症历史候选基因的现状(例如,COMT、DISC1、DTNBP1和NRG 1)。对其中24个基因的初步研究明确评估了关于精神分裂症的常见变异假设。我们的评估包括对候选基因文献的荟萃分析,纳入迄今为止发表的最大的精神分裂症基因组研究结果,发表这些基因的知情研究人员的评级,以及24位精神分裂症遗传学家的评级。根据目前的经验证据和大多数知情的意见一致的评估,似乎历史上的候选基因文献并没有产生明确的见解精神分裂症的遗传基础。历史候选基因研究没有实现其主要目标的一个可能原因是统计能力不足。然而,这些早期研究中所体现的巨大努力无疑为精神分裂症基因组方法的当前成功奠定了基础。
Prior to the genome-wide association era, candidate gene studies were a major approach in schizophrenia genetics. In this invited review, we consider the current status of 25 historical candidate genes for schizophrenia (e.g., COMT, DISC1, DTNBP1, and NRG1). The initial study for 24 of these genes explicitly evaluated common variant hypotheses about schizophrenia. Our evaluation included a meta-analysis of the candidate gene literature, incorporation of the results of the largest genomic study yet published for schizophrenia, ratings from informed researchers who have published on these genes, and ratings from 24 schizophrenia geneticists. On the basis of current empirical evidence and mostly consensual assessments of informed opinion, it appears that the historical candidate gene literature did not yield clear insights into the genetic basis of schizophrenia. A likely reason why historical candidate gene studies did not achieve their primary aims is inadequate statistical power. However, the considerable efforts embodied in these early studies unquestionably set the stage for current successes in genomic approaches to schizophrenia.
