摘要: 目的:探讨在中国北方汉族人群中PTGDS基因rs3814500位点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141个由精神分裂症患者及其健康父母组成的核心家系的基因型,应用遗传统计学方法进行单倍型相对风险分析(HRR)和传递不平衡检验(TDT)。结果: 患者组和父母组PTGDS基因的rs3814500位点基因型频数分布均符合Hardy-Weinberg平衡定律(P>0.05);HRR分析结果显示,父母传递和未传递给患病子女的等位基因频数分布差异无显著性(χ2=0.095, P>0.05);TDT分析结果显示,杂合子父母双亲的2个不同等位基因传递概率没有偏离50%(χ2=0.103,P>0.05)。结论: 在中国北方汉族人群中PTGDS基因rs3814500位点基因多态性与精神分裂症可能无关联。

Abstract: To investigate the genetic association between the polymorphism of rs3814500 site on PTGDS gene and schizophrenia in Han population from the north of China.Methods PCR-RFLP analysis was employed to detect the genotype of PTGDS gene in 141 family trios consisting of fathers,mothers and affected offsprings with schizophrenia.Haplotype relative risk(HRR) analysis and transmission disequilibrium test(TDT) were used to analysis the genotype data.Results The genotypic frequency of the PTGDS gene did not deviate from Hardy-Weinberg equilibrium in both patient group and parent group(P>0.05); HRR analysis did not show allelic association with the PTGDS gene(χ2=0.095, P>0.05);TDT analysis did not show preferential transmission of the two alleles(χ2=0.103,P>0.05). Conclusion There is no genetic association between the polymorphism of rs3814500 site on PTGDS gene and schizophrenia in Han population from the north of China.
