| 摘 要： | 目的 探讨中国北方汉族人群中NTNG1基因rs4132604、rs2218404、rs1373336基因多态性与精神分裂症的关系.方法 采用聚合酶链式反应-限制性内切酶片段长度多态性(PCR-RFLP)的方法,检测中国北方汉族316例精神分裂症患者及311例健康对照者的基因型,应用遗传统计学方法进行等住基因型及等位基因频率分析、单倍型分析.结果 病例组和对照组NTNG1基因的rs4132604、rs2218404、rs1373336基因型频数分布均符合Hardy-Weinberg平衡定律(P>0.05);rs4132604等位基因频率(χ2=7.86,P=0.01)和基因型分布(χ2=7.67,P=0.02)在病例组和对照组间存在显著性差异,提示该基因在中国北方汉族人群中同精神分裂症的发病明显相关.病例组与对照组比较,rs2218404、rs1373336等位基因频率和基因型分布未见显著性差异.在单倍型分析中,rs4132604与rs2218404中的GG(χ2=6.11,P=0.01)和TG(χ2=5.28,P=0.02)、rs2218404与rs1373336中的GT(χ2=5.38,P=0.02)和GC(χ2=4.72,P=0.03)、三者中GGT(χ2=13.40,P=0.00)和TGT(χ2=6.56,P=0.01),两组间存在显著性差异.结论 NTNG1基因的rs4132604多态位点同精神分裂症存在关联.IWNG1基因的rs4132604、rs2218404、rs1373336构成的单倍型上存在同精神分裂症发病的相关位点.

| Abstract: | Objective To investigate the genetic association between the polymorphism of rs4132604 site,rs2218404 site and rs1373336 site on NTNG1 gene and schizophrenia in Han population from the north of China.Methods PCR-RFLP analysis was used to detect the genotype of NTNG1 gene in 316 patients and 311 controls.Inheritance statistics methods were used to analysis the genotype,allele frequencies and haplotype.Results The genotypic frequency of the NTNG1 gene did not deviate from Hardy-Weinberg equilibrium in both pa... |
