全面性癫癎伴热性惊厥附加症家系GABRB2基因测序研究
Sequencing Analysis of GABRB2 Gene in a Generalized Epilepsy with Febrile Seizure Plus Family
【摘要】 目的对全面性癫伴热性惊厥附加症(GEFS+)侯选基因GABRB2进行测序研究。方法设计GABRB2外显子-内含子交界处内含子引物,采用PCR直接测序法,对一GEFS+家系GABRB2编码区全部11个外显子进行测序分析。结果患儿GABRB2基因外显子2,mRNA第133个碱基发现一新的C/G多态性。结论该家系未发现GABRB2基因编码区的突变;所显示的mRNA的单个碱基多态性对以后其他癫家系的连锁分析及GABRB2 mRNA、基因功能研究均有重要意义。
【Abstract】 Objective Sequencing analysis of candidate gene GABRB2 in generalized epilepsy with febrile seizure plus(GEFS~+).Method Intron primers were designed around the splicing sites of 11 exons and PCR-direct sequencing method was performed in all 11 exons of GABRB2 gene.Result A novel C/G polymorphism in exon 2(mRNA G133 C) had been detected in patients.Conclusion The new single nucleotide polymorphism(SNP) from GABRB2 exon 2 is useful for SNP linkage mapping in other familial epileptic syndrome and mRNA functional analysis of GABRB2 gene in the future.
