目的 探讨γ-氨基丁酸B受体B1亚单位(gamma-aminobutyric acid B receptor 1,GABBR1)基因G1465A多态与中国汉族人青少年肌阵挛癫痫(juvenile myoclonic epilepsy,JME)的关系。 方法 柱层析法提取血细胞基因组DNA,应用PCR-RFLP检测105例青少年肌阵挛癫痫患者和100例中国汉族正常人GABBR1基因G1465A多态基因型。 结果 ① A/A基因型频率在JME组(0.524)显著高于对照组(0.360)(P0.05)。② A等位基因频率在JME组(0.695)显著高于对照组(0.560)(P0.05)。③ A等位基因频率患JME的相对风险度为1.792(95%CI:1.195~2.688)(P0.05)。 结论 GABBR1基因G1465A多态与中国汉族人群JME相关,A等位基因可能是JME的易感基因。
Abstract
Objective To investigate the relationship between gamma-aminobutyric acid B receptor 1 (GABBR1) gene G1465A polymorphism and juvenile myoclonic epilepsy (JME) in Chinese Han nationality. Methods EDTA-blood specimens were collected from the unrelated individuals of Han nationality in Chongqing. DNA samples were extracted with column chromatography. The G1465A polymorphism was detected by PCR-RFLP and DNA sequencing for 105 individuals of JME group and 100 controls. Results The frequency of A/A genotype was significantly higher in JME group (0.524) than that in control group (0.360) (P0.05). The frequency of A allele was significantly higher in JME group (0.695) than that in control group (0.560) (P0.05). The odd ratio for the A allele carrier with JME was 1.792 (95% CI: 1.195-2.688) (P0.05). Conclusion The G1465A polymorphism of GABBR1 gene confers a highly increased susceptibility to JME in Chinese Han nationality. Moreover
the A allele may be the susceptible gene of JME patients.
