摘要: 目的 探讨促肾上腺皮质激素释放激素结合蛋白基因4个标签单核苷酸多态性(tag single nucleotide polymorphism,Tag SNP)位点(rs7721799、rs32897、rs7718461、rs10062367)与云南汉族个体精神分裂症 及患者攻击行为的相关性。 方法 采用病例对照关联分析,建立复合扩增体系,应用改良的多重高温连接 酶检测反应技术检测163例汉族精神分裂症患者(其中伴攻击行为患者81例,不伴攻击行为患者82例)和 345例健康汉族个体CRHBP 基因4个SNP位点基因型,采用SPSS 19.0、Haploview 4.2、PHASE 2.1软件进 行统计学分析。 结果 CRHBP 基因 rs7718461 位点以外的 3 个 SNP 位点与精神分裂症的发病无关联(P> 0.05)。rs7718461 位点携带 GG 或 GA 基因型患者的攻击行为相对风险为携带 AA 基因型患者的 4.903 倍 (P<0.05)。 结论 CRHBP基因可能与云南汉族精神分裂症的发生无关联,但rs7718461的AA基因型可能降低精神分裂症患者攻击行为发生的风险。

Abstract: Objective To explore the correlation between 4 tag single nucleotide polymorphisms (Tag SNP) sites (rs7721799, rs32897, rs7718461, rs10062367)of corticotropin releasing hormone binding protein (CRHBP) and schizophrenia and aggressive behavior in the Yunnan Han population. Methods Casecontrol correlation analysis was used to establish a complex amplification system. Improved multiplex ligase detection reaction(iMLDR)technology was used to detect the genotypes of 4 SNP sites of CRHBP gene of 163 Han schizophrenic patients (including 81 patients with aggressive behavior, 82 patients without aggressive behavior)and 345 healthy Han individuals, which were analyzed statistically by SPSS 19.0, Haploview 4.2 and PHASE 2.1 software. Results There was no correlation between the 3 SNP sites of CRHBP gene and the onset of schizophrenia except for the rs7718461 site (P>0.05). The relative risk of aggressive behavior of patients carrying GG or GA genotype at rs7718461 site were 4.903 times higher than those carrying AA genotype (P<0.05). Conclusion The CRHBP gene may not be associated with the occurrence of schizophrenia in Yunnan Han population, but AA genotype of rs7718461 may reduce the risk of aggressive behavior in schizophrenia patients.
