妊娠期肝内胆汁淤积症患者多药耐药3基因外显子8和12突变的研究
Journal of Practical Obstetrics and Gynecology（2012）
Abstract
目的:研究多药耐药3( MDR3)基因外显子8和12突变与妊娠期肝内胆汁淤积症(ICP)的关系,探讨ICP的发生机制.方法:从29例ICP患者及32例正常孕妇的外周血中提取DNA,聚合酶链反应(PCR)扩增MDR3基因外显子8和12,对PCR产物进行DNA测序分析.结果:ICP患者和对照组PCR均扩增出目的片段,且存在多态性位点G711A及A1260G,两组的8号外显子基因型频率和12号外显子基因型频率比较,差异均有统计学意义(P＜0.05,P＜0.01).结论:云南临沧地区ICP的发生可能与MDR3外显子8和12的突变有关.
