中国汉族人群中RELN基因rs7341475位点与精神分裂症的相关性分析

Association of RELN SNP rs7341475 with schizophrenia in the Chinese population

  • 摘要: 精神分裂症是一种常见的复杂精神疾病。大量的实验证据表明, 遗传因素在精神分裂症的发生中起到了重要的作用。截至目前, 有报道称至少100个基因与精神分裂症相关, 但它们在不同人群中的重复性不好。在这些基因中, RELN在多个人群中都被证实与精神分裂症相关, 表明它可能是一个真实的易感基因。目前, 在RELN基因上有很多个单核苷酸多态性位点被证实与精神分裂症相关, 其中研究最多的是通过全基因组关联分析发现的在RELN基因第四个内含子中的单核苷酸多态性位点 rs7341475, 它被证明与精神分裂症的发生相关。为了验证该位点在中国人群中是否与精神分裂症相关, 作者对来自中国玉溪的病例——对照样本(400位患者和400位正常人)进行了遗传分析。结果显示, 在该样本中rs7341475与精神分裂症不相关, 这表明rs7341475在中国人群中可能不是致病多态性位点。

     

    Abstract: Schizophrenia is a common and complex psychiatric disorder. Significant evidence has suggested that genetic factors play pivotal roles in the etiology of schizophrenia. More than 100 schizophrenia candidate genes have been reported; however, many of them do not have satisfactory replications among different populations. Among these genes, RELN is thought to be associated with schizophrenia in many populations, suggesting it is a real risk gene for this disorder. Identified in the GWAS study, single nucleotide polymorphism (SNP) rs7341475, located in intron 4 of RELN, has been successfully replicated in subsequent investigations, implying its potential contribution to schizophrenia susceptibility. To investigate the association of rs7341475 with schizophrenia in Chinese populations, a case-control association analysis was conducted with samples from Yuxi (400 cases and 400 controls) in southwestern China. The results do not indicate any association of rs7341475 with schizophrenia, which suggests it is not a risk SNP for schizophrenia in Han Chinese.
