目的研究新疆地区汉族房颤患者GGCX基因rs11676382位点多态性及其与华法林稳定剂量的相关性。方法从长居新疆地区的汉族房颤患者中,收集200例获得华法林稳定剂量的病例资料,所有入选者均采集外周血提取基因组DNA,采用聚合酶链反应,限制性片段长度多态性技术(PCR-RF凹)检查患者GGCX基因您11676382多态性的分布。比较不同基因型受试者之间华法林用量的差异。结果200例受试者中,GGCX基因阳11676382位点CC、CG和GG基因型的例数分别为150例(82.5%)、48例(16.5%)和2例(1.0%);C和G等位基因的频率分别为99%、1%;所选人群GGCX(rs11676382)等位基因频率和基因型频率均符合HaZy—Weinberg平衡(x^2=0.744,P=0.388),本组受试者稳定剂量范围是1.25,6.88mg/d,平均(3.22±1.12)mg/d。基因型为CC、CG和GG的受试者华法林稳定剂量分别为(5.93±1.33)mg/d、(3.22±0.88)mg/d和(3.16±1.40)mg/d。经秩和检验分析,GGCX(M11676382)多态位点与华法林稳定剂量显著相关(x^2=6.094,P=0.047)。结论获得了长居新疆地区汉族房颤患者的GGCX基因巧11676382多态性。同时发现基因型CC与高剂量相关,GG与低剂量相关,该位点可作为预测个体华法林稳定剂量的一项指标。
Objective In order to study if The Correlation between GGCX gene polymorphism and the relationship on warfarin stable dosage in Xinjiang han nationality with atrial fibrillation (Atrial Fibrillation AF) . Methods The blood was collected from 200 han nationality people who live in Xinjiang for long time and have atrial fibrillation, DNA was extracted, polymerase chain reac- tion-restriction enzyme fragment length polymorphism (PCR-RFLP) was used and identified by agarose eletrophoresis to analyse GGCX genotype and allele distribution. Results The result showed that GGCX gene CC, CG and GG gene type frequency we-re found respectively 82. 5 % , 16. 5 % and 1 % , and C and G allele frequency were 99 % , 1%. The GGCX (rs11676382) allele and genotype frequencies of selected crowd were the I-Iardy-Weinberg balance ( x^2=0. 744, P = 0. 388 ) . The subject on a stable dose range was 1. 25 -6. 88 mg/d, mean 3.22 ± 1.12 rag/d, The genotype of themwere CC: 5.93 ±1.33 mg/d, CG: 3.22 ±0.88 mg/d and GG: 3.16 ±1.14 mg/d. The Kruskal-Wallis test analysis : GGCX (rs11676382) polymorphisms were significantly associated with warfarin stable dose ( x^2 = 6. 094, P = 0. 047 ) . Conclusion Obtained GGCX gene rs11676382 polymorphism of xinjiang han patients with atrial fibrillation. The authors consider that warfarin high doses associated with genotype GGCX and low-dose-related. This can be used as an indicator to pre- dict an individual stable doses of warfarin.
