摘  要:目的探讨L型钙离子通道cdC亚基(calcium channel,voltage-dependent,Ltype,Mpha 1C subunit,CACNA1C)基因多态性与精神分裂症的关联。方法纳入1432例精神分裂症患者及1153名正常对照,采用连接酶检测一聚合酶链反应(1igasedetectionreaction—polymerasechainreaction,LDR.PCR)方法对CACNAlC基因rs1006737、rs1024582位点进行基因分型,观察其等位基因及基因型与精神分裂症发病风险的关系。结果患者组rs1006737位点的基因分布(A、G等位基因频率分别为5.3%、94.7%,AA、AG、GG基因型频率分别为O.2%、10.2%、89.6%)与对照组(A、G等位基因频率分别为4.0%、96.0%,AA、AG、GG基因型频率分别为0.4%、7.4%、92.3%)比较,差异有统计学意义(P〈0.05),患者组rsl024582位点的基因分布(A、G等位基因频率分别为4.9%、95.1%,AA、AG、GG基因型频率分别为0.2%、9.3%、90.5%)与对照组(A、G等位基因频率分别为4.0%、96.O%,AA、AG、GG基因型频率分别为0.1%、7.8%、92.1%)比较,差异无统计学意义(P〉0.05)。rs1006737位点G等位基因(OR=1.332,95%CI=1.016~1.746)与精神分裂症相关联(P〈0.05)。结论本研究支持在汉族人群中CACNA1C基因rs1006737位点多态性与精神分裂症相关联。Objective To explore the relationship of calcium channel,vohage-dependent,L type,alpha 1C subunit (CACNA1C) gene polymorphism with schizophrenia. Methods A total of 1 432 patients with schizophrenia and 1 153 healthy controls were selected using Ligase Detection Reaction-Polymerase Chain Reaction(LDR-PCR) to analyze the genotypes of CACNA1C gene (rs1006737 and rs1024582).Results The allelic and genotypic distributions in rs1006737 between patients with schizophrenia (A, G allele:5.3%,94.7% ; A/A, A/G, G/G genotypes : 0.2%, 10.2%, 89.6% ) and healthy controls ( A, G allele: 4.0%,96.0% ; A/A, A/G, G/G genotypes : 0.4%, 7.4%, 92.3% ) had statistically significance after analysis (P〈0.05) .The allelic and genotypic distributions in rs1024582 between patients with schizophrenia (A, G allde :4.9%, 95.1% ; A/A, A/G, G/G genotypes : 0.2%, 9.3%, 90.5% ) and healthy controls ( A, G allele : 4.0%,96.0% ; A/A, A/G, G/G genotypes :0.1%,7.8%, 92.1% ) did not have statistically significance after analysis (P〉0.05).The G allele of rs1006737 (OR= 1.332,95%CI= 1.016-1.746) was associated with the risk of schizophrenia (P〈 0.05 ). Conclusion This research supports that CACNA1C gene rs 1006737 polymorphism is associated with schizophrenia in Han Chinese.
