为了研究脯氨酰羟化酶2 (EGLN1或PHD2)基因5′UTR区和内含子区的单核苷酸多态性(SNP)与高海拔低氧适应的相关性, 文章使用Sequenom MassArray基因分型系统对152例西藏藏族(海拔3 650 m)和192例湖北汉族(海拔500 m) EGLN1基因的6个单核苷酸多态性位点(rs2066140、rs2808584、rs2491405、rs2486741、rs2486734和rs21533646)进行基因分型, 并进行单倍型构建和分析。结果发现：6个SNP位点的纯合子基因型在高海拔和低海拔群体间均具有统计学差异(P<0.05)。单倍型分析显示, 单倍型G-G(rs2066140和rs2808584)和G-C(rs2486741和rs2486734)的频率在高海拔群体中高于低海拔群体(P<0.05), 单倍型C-A(rs2066140和rs2808584)和C-T(rs2486741和rs2486734)的频率在高海拔群体中低于低海拔群体(P<0.05)。研究结果提示, EGLN1基因6个SNP位点的纯合子基因型和所构建的单倍型与高海拔低氧适应相关。

To investigate the association between SNPs located in 5′UTR and intron of prolyl hydroxylase 2 (EGLN1 or PHD2) and adaptation to high-altitude hypoxia, the SNPs (rs2066140, rs2808584, rs2491405, rs2486741, rs2486734 and rs21533646) of EGLN1 gene were genotyped using Sequenom MassArray genotyping system in 152 unrelated healthy Tibetan individuals (3 650 m altitude) and 192 Han (5 00 m altitude), and the haplotypes of these SNPs were constructed and analyzed. Our results showed all the homozygous genotypes of six SNPs loci were significantly different between the two groups (P<0.05). The frequencies of haplotypes G-G (rs2066140 and rs2808584) and G-C (rs2486741 and rs2486734) of high-altitude group were significantly different from low-altitude group (P<0.05). In addition, the frequencies of haplotypes C-A (rs2066140 and rs2808584) and C-T (rs2486741 and rs2486734) of high-altitude group were significantly lower than those in low-altitude group (P<0.05). Our results indicate that the polymorphism of homozygous genotype in six SNPs and their haplotypes were associated with adaptation to high-altitude hypoxia.
