摘要: 目的:探讨中国北方汉族人群13q32区域亲核素β3(KPNB3)基因多态性与精神裂症各种临床表型的关系。方法:收集752例中国北方汉族人群精神分裂症患者和909例健康对照全血样品,提取基因组DNA,采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)的方法,检测KPNB3基因rs626716单核苷酸多态性位点基因型。应用拟合优度χ2检验分析基因型分布频率是否符合Hardy-Weinberg平衡定律,应用χ2检验和数量性状分析分别进等位基因、基因型以及各种临床表型的关联性分析。结果:精神分裂症病例组和健康对照组rs626716位点基因型分布频率均符合Hardy-Weinberg平衡(P>0.05)。等位基因关联分析表明,病例组和对照组等位基因C和T的频率分布差异无显著性(P>0.05);基因型关联分析表明,病例组和对照组C/C、C/T和T/T 3种基因型的频率分布差异无显著性(P>0.05);等位基因频率与精神分裂症各种临床表型的关联性分析结果表明,rs626716与精神分裂症各种临床表型不相关(P>0.05)。结论: KPNB3基因rs626716位点可能与中国北方汉族人群精神分裂症发病及其临床表型无关,但是不能排除该基因其他SNPs位点与精神分裂症有关联。

Abstract: To investigate the genetic association between KPNB3 gene in chromosome 13q32 and schizophrenic phenotypes in Han population from North China. Methods Genomic DNA was isolated from the whole blood samples.A single nucleotide polymorphism,rs626716 (Pst I site) present in the KPNB3 gene,was detected using PCR-based restriction fragment length polymorphism analysis among 752 Chinese Han patients with schizophrenia (case group) and 909 ethnicity-matched healthy controls (control group).The Hardy-Weinberg equilibrium for genotypic distribution was estimated by the goodness-of-fit χ2 test.The frequencies of alleles and genotypes of KPNB3 gene and the relationship between allelic frequencies and the clinical phenotypes of schizophrenia were statistically computed. Results The goodness-of-fit χ2 test showed that the genotypic distributions of rs626716 were not deviated from Hardy-Weinberg equilibrium in both case group and control group (P>0.05).The χ2 test did not show allelic association and genotypic association for rs626716 (P>0.05).There were no correlations between allelic or genotypic frequencies and the clinical phenotypes of schizophrenia (P>0.05). Conclusion rs626716 locus may not be associated with schizophrenic phenotypes,but the correlation between the other SNPs locus at KPNB3 gene and schizophrenia could not be ruled out.
