摘要: 目的 在中国人群中验证精神分裂症易感基因是否与13q连锁.方法 收集4个精神分裂症高发家系,采集家系成员外周血,提取DNA.在13q14-13q33选取7个微卫星标记,进行部分基因组扫描,采用GENEHUNTER2.1软件进行单点和多点的参数、非参数连锁分析.结果 单点非参数连锁分析D13S156、D13S170、D13S265、D13S159、D13S158位点NPL值分别为1.40、2.25、2.06、1.71和1.39.多点非参数连锁分析得到约50cM的阳性区域.单点和多点参数连锁分析也在一些位点得到阳性结果.结论 13q22.1-13q33.1染色体区域可能存在精神分裂症的易感基因.

Abstract: Objective To explore the genetic susceptibility loci on 13q of schizophrenia in Chinese pedigrees.Methods 4 multiplex schizophrenia pedigrees were collected.Blood samples were collected from the families and genomic DNA was extracted.7 microsatellite markers on 13q14-13q33 were evaluated.Linkage analyses were carried out by GENEHUNTER 2.1 software.Results The results of single point-point nonparametric linkage analyses are positive at 5 consecutive locus.The NPL score are 1.40,2.25,2.06,1.71 and 1.39 at D13S156,D13S170,D13S265,D13S159,and D13S158 respectively.A 50cM positive region was observed by multipoint nonparametric linkage analyses.Positive regions were also observed by single-point and multipoint parametric linkage analyses.Conclusion Loci on 13q22.1-13q33.1 may influence susceptibility to schizophrenia.
