摘要 目的 探讨中国人群中家族性精神分裂症易感基因与 1号染色体的分子遗传学关系。方法用基因组扫描的方法 ,选择了平均分布在 1号染色体上的 2 9个标记 ,对 32个家族性精神分裂症家系样本进行易感基因扫描。结果 参数连锁分析结果 ,在隐性模型下 ,多点连锁在 2 6 2 .5 2 c M位置得到最大异质性 L od分为 1.70 ;非参数连锁分析结果 ,2 6 2 .5 2 c M位置处得到最大的多点非参数连锁分为 1.71(P=0 .0 46 ) ,其次是 149.70 c M位置处得到多点非参数连锁分为 1.37(P=0 .0 86 ) ,分别对应于标记 D1S2 0 6、D1S42 5位点的位置。结论 进一步支持在染色体 1q上可能存在家族性精神分裂症的易感基因。 Objective: To explore the molecular genetic relationship between chromosome 1 and susceptibility genes for familial schizophrenia in Chinese population. Methods: A genome scanning was conducted in 32 multiplex pedigrees from Chinese population by using 29 microsatellite markers on chromosome 1. Results: Multipoint parametric analysis detected a maximum heterogenicity Lod of 1. 70 at 262. 52 cM under a recessive model; multipoint non-parametric analysis detected a maximum nonparameter linkage (NPL) of 1. 71 (P = 0.046) at 262. 52 cM, then 1. 37 (P = 0.086) at 149. 70 cM, corresponding to marker D1S206 and D1S425 respectively. Conclusion: These results give further supports to the presence of susceptibility genes on chromosome 1q for familial schizophrenia.
