摘要 目的研究福州地区人群中VKORC1-1639G/A基因多态性分布,探索VKORC1^-1639G/A基因多态性对华法林剂量及血药浓度的影响,为建立华法林个体给药模型提供依据。方法应用PCR-RFLP法以及已建立好的HPLC法测定上述患者的基因多态性的分布情况和血浆中华法林的血药浓度。结果50例患者中,VKORC1-1639G/A基因多态性共检测到3种基因型,AA型为86%,AG型为12%,GG型为2%;所需华法林平均剂量,AA型为1日(2.30±0.76)mg,AG型为1日(3.17±0.92)mg,GG型为1日7.5mg;平均血浆稳态华法林浓度,AA型为(727.776±372.480)ng·mL^-1,AG型为(1074.922±458.963)ng·mL^-1,GG型为3258.372ng·mL^-1。结论VKORC1-1639G/A基因多态性对华法林剂量及血药浓度有明显影响。
