Tetraspanin-18 (TSPAN18) 可能在与多巴胺诱导的皮质神经元凋亡相关的钙信号传导中发挥作用,并被认为是精神分裂症 (SCZ) 发病机制的重要机制。此外,一项全基因组关联研究 (GWAS) 确定 TSPAN18 可能是 SCZ 的易感基因。为了验证这些发现并揭示不同遗传模型的影响,通过 SNPscan 方法对 443 名 SCZ 患者和 628 名汉族血统对照者的 TSPAN18 基因的 7 个单核苷酸多态性 (SNP) 进行了分析。使用不同模型(即加性、显性和隐性模型)进行单 SNP、基因型和关联分析,并将已发表的数据集(2062 个病例和 2053 个对照)与我们的结果相结合,以确定 SNP 对 SCZ 的遗传效应。根据我们的实验和荟萃分析结果,我们观察到 TSPAN18 基因的基因型和等位基因分布在中国汉族人群中没有显示出任何显着关联。我们的研究结果表明,TSPAN18 基因不太可能是汉族人精神分裂症的主要易感基因。
Tetraspanin-18 (TSPAN18) potentially plays a role in the calcium signaling that is associated with dopamine-induced cortical neuron apoptosis and is considered to be an important mechanism in the pathogenesis of schizophrenia (SCZ). Furthermore, a genome-wide association study (GWAS) identified TSPAN18 as a possible susceptibility gene for SCZ. To validate these findings and reveal the effects of different inheritance models, seven single nucleotide polymorphisms (SNPs) of the TSPAN18 gene were analyzed in 443 patients with SCZ and 628 controls of Han Chinese descent via the SNPscan method. Single SNP, genotype, and association analyses with different models (i.e., additive, dominant, and recessive models) were performed, and the published datasets (2062 cases and 2053 controls) were combined with our results to determine the inheritance effects of the SNPs on SCZ. We observed genotypes and allele distributions of TSPAN18 gene did not show any significant associations in the Han Chinese population based on our experimental and meta-analytical results. Our findings indicate that the TSPAN18 gene is unlikely to be a major susceptibility gene for schizophrenia in Han Chinese.
