摘要:
目的 探讨中国汉族人群细胞色素氧化酶P450 2C9(CYP2C9)基因以及维生素K环氧化物还原酶复合体1(VKORC1)基因多态性对华法林用药的影响。方法 首先抽取无抗凝障碍的汉族人群受试者200例利用基因测序法进行CYP2C9 和VKORC1基因分型(正常对照组)。并收集临床使用华法林稳定维持剂量的汉族人群患者114例(服用华法林药物组),记录患者年龄、性别、身高、体质量以及体表面积等,检测基因型并结合体征差异及临床稳定剂量进行分析。结果 正常对照组的CYP2C9基因型检测有CYP2C9*1/*1型186例(93%),未发现CYP2C9*1/*2型,CYP2C9*1/*3型14例(7%); VKORC1-1639A/G基因型:AA型179例(89.5%),GA型21例(10.5%),未发现GG型(0.0%); 服用华法林药物组的CYP2C9*1/*1型104例(91.2%),CYP2C9*1/*3型10例(8.8%),CYP2C9*1/*1型患者华法林平均维持剂量高于CYP2C9*1/*3型患者[(2.13±0.83)mg/dvs(1.61±1.17)mg/d,P<0.05]。VKORC1(-1639G>A)基因型检测有102例患者为突变纯合子AA型(89.5%),12例患者为杂合子GA型(10.5%),未发现纯合子GG型患者,GA型患者华法林平均维持剂量明显高于AA型[(3.34±1.07)mg/d vs(1.63±0.45)mg/d,P<0.01]。正常人群组与服用华法林药物组基因型在CYP2C9*3(1075C/A)(P=0.926)和VKORCl -1639A/G突变上的差异无统计学意义(P=0.812)。结论 中国汉族人群存在CYP2C9*3 A/C 和VKORC1-1639G/A 的基因多态性,且不同基因型患者间华法林用量存在差异。
