摘要: 目的 探讨精神分裂症人群胆囊收缩素(cholecystokinin,CCK)基因-45C/T位点遗传多态性及其法医学意义。 方法 采用双向等位基因特异性PCR方法对中国北方汉族群体207例精神分裂症患者(患者组)和202例健康个体(对照组)CCK基因-45C/T位点多态性进行检测。采用χ2检验对照组人群中基因型分布是否符合Hardy-Weinberg平衡并比较两组人群中基因型和等位基因频率分布的差异。 结果 对照组人群中基因型频率分布均符合Hardy-Weinberg平衡,患者组与对照组基因型与等位基因频率分布差异无统计学意义(P>0.05)。性别分层分析显示,女性患者组等位基因T的频率显著高于女性对照组(P=0.044)。 结论 CCK基因-45C/T位点T等位基因可能与女性精神分裂症存在阳性关联,可能有助于精神分裂症的鉴定。

Abstract: Objective To investigate the polymorphism of cholecystokinin(CCK) gene -45C/T of schizophrenia and its application in forensic medicine. Methods Bidirectional allele specific PCR was used to detect CCK gene -45C/T polymorphisms in 207 schizophrenic patients (case group) and 202 healthy individuals (control group) of the Han population in northern China. The χ2 test was used to identify Hardy-Weinberg equilibrium of the genotype distribution in control group. The differences of genotype and allele frequencies distributions were compared between two groups. Results Distributions of the genotype frequencies satisfied the law of Hardy-Weinberg equilibrium in control group. The differences between genotypic frequencies and allele frequencies were not statistical significance in case group and control groups(P>0.05). Gender-stratified analysis showed that frequency of allele T in female case group was statistically higher than that in female control group(P=0.044). Conclusion CCK gene -45C/T locus T allele may be positively associated with schizophrenia in female population and useful in schizophrenia identification.
