摘要:

既往研究证实VKORC1CYP2C9多态性对华法林的抗凝作用影响较大, 但是其它常见遗传变异性对华法林常规剂量影响仍不明确。本研究目标是调查其他候选基因(CYP4F2, CACNA1C, STX4)单核苷酸多态性(SNPs)对中国心血管疾病患者日常华法林稳定剂量(DWMD)的影响。北京医院207名应用华法林的心血管疾病患者纳入研究, 用药后一天抽血并提取全血DNA, 应用LDR(连接酶检测反应)方法检测5个基因VKORC1, CYP2C9, CYP4F2, CACNA1CSTX49SNPs(rs9923231, rs9934438, rs7294, rs1799853, rs1057910, rs4086116, rs2108622, rs216013, rs10871454), 应用单因素分析和多重线性回归分析来分析SNP和其他因素(包括体表面积, 合并他汀类药物等变量)DWMD的关系。4个位点(CYP2C9基因的rs9923231, rs9934438, rs7294STX4基因的rs10871454)DWMD有显著影响。多元线性回归模型显示, STX4基因的rs10871454, BSA, 合并他汀类药物和CYP2C9rs1057910DWMD的影响最显著并进入最后的公式。并且在所有基因位点中STX4上的rs10871454对华法林的剂量影响最大, 这表明它可作为预测中国患者的华法林稳定剂量的关键基因因素。

Abstract:

VKORC1 and CYP2C9 have been shown to be strongly associated with Warfarin dosing. However, it is still unclear whether other common genetic variants also contribute to the variation in Warfarin dosing. In the present study, we aim to investigate possible effects of single nucleotide polymorphisms (SNPs) in other candidate genes (CYP4F2, CACNA1C and STX4), as well as several factors, on stable daily Warfarin dosage (DWMD) in Chinese cardiovascular disease patients. 207 cardiovascular disease patients treated with Warfarin were recruited from Beijing Hospital. DNA was extracted from the blood samples collected one day after Warfarin administration. Nine SNPs (i.e. rs9923231, rs9934438, rs7294, rs1799853, rs1057910, rs4086116, rs2108622, rs216013 and rs10871454 in five genes (i.e. VKORC1, CYP2C9, CYP4F2, CACNA1C and STX4) were analyzed using ligase detection reactions (LDR). Univariate analyses and multiple linear regression analyses were performed to analyze the associations between SNPs and other factors (i.e. body surface area (BSA), Statin medication) and DWMD. Four SNPs (i.e. rs9923231, rs9934438, rs7294 in VKORC1 and rs10871454 in STX4) had significant statistically effects on DWMD. The multiple linear regression model showed that rs10871454 in STX4, BSA, statin medication, and rs1057910 in CYP2C9 were the significant independent covariates of DWMD. SNP (rs10871454) in STX4 had the strongest effect on Warfarin dosing among the examined candidate genes, indicating that it might serve as a key genetic factor for prediciting the Warfarin maintenance dose in Chinese patients.
