摘要:

探讨EPAS1基因rs1868092位点多态性与藏族人群高原红细胞增多症(HAPC)的相关性。方法:用TaqMan探针法对80例藏族HAPC患者和85例藏族健康受试者EPAS1基因SNP rs1868092位点进行检测,分析SNP rs1868092位点与HAPC发生的相关性。结果:HAPC患者EPAS1基因rs1868092位点GG基因型的频率(11.250% vs. 2.353%P=0.005OR=7.37595%CI1.50836.066)和等位基因G的频率(33.125% vs.16.471%P<0.001OR=2.51295%CI1.4904.234)显著高于健康受试者,差异有统计学意义;显性模式下HAPC患者的GG+AG基因型频率(P=0.002OR=2.77495%CI1.4665.249)显著高于健康受试者,差异有统计学意义。结论:EPAS1基因SNP rs1868092 位点的G等位基因是西藏地区藏族人群发生HAPC的风险因子。

Abstract:

ObjectiveTo explore the correlation between the polymorphism of rs1868092 in EPAS1 gene and high altitude polycythemia HAPCin Tibetan population. MethodsA TaqMan probe was used to examine of the EPAS1 gene SNP rs1868092 locus in 80 Tibetan HAPC patients and 85 healthy Tibetan analysis to investigate the correlation between the SNP rs1868092 locus and the occurrence of HAPC. ResultsThe frequency of EPAS1 gene rs1868092 genotype GG 11.250% vs. 2.353%P=0.005OR=7.37595%CI is 1.508-36.066and allele G33.125% vs. 16.471%P<0.001OR=2.51295%CI is 1.490-4.234was significantly higher than that in the healthy subjectswith statistical significance. Under the dominant modelthe frequency of GG+AG genotypes in HAPC patientsP=0.002OR=2.77495%CI is 1.466-5.249was significantly higher than that in healthy controlswith statistical significance. ConclusionThe G allele of the rs1868092 SNP locus of the EPAS1 gene is a risk factor for Tibetan population to develop HAPC.
