Single nucleotide polymorphisms (SNPs) in the collagen type I (COL1A1) gene have been shown to be significantly associated with high myopia in a Japanese population. This present study was conducted to investigate whether COL1A1 is associated with high myopia in a Han Chinese population.
High myopia is defined by a spherical equivalent of less than or equal to -6.00 diopter sphere and an axial length longer than or equal to 26.0 mm in the affected eye. We genotyped rs2075555 and rs2269336 SNPs in COL1A1 in a Ha n Chinese group composed of 697 high myopia patients and 762 normal controls.
Neither of the two SNPs showed significant association with high myopia (p(allelic)=0.252 for rs2075555, and p(allelic)=0.699 for rs2269336).
Our study revealed that SNPs in COL1A1 are not significantly associated with high myopia in the Han Chinese population.
在日本人群中,I型胶原蛋白(COL1A1)基因中的单核苷酸多态性(SNP)已被证明与高度近视显著相关。本研究旨在调查COL1A1基因是否与汉族人群中的高度近视相关。
高度近视定义为患眼等效球镜小于或等于-6.00屈光度且眼轴长度大于或等于26.0毫米。我们对由697例高度近视患者和762例正常对照组成的汉族人群中的COL1A1基因rs2075555和rs2269336单核苷酸多态性进行了基因分型。
两个单核苷酸多态性均未显示与高度近视有显著关联(rs2075555的p(等位基因)=0.252,rs2269336的p(等位基因)=0.699)。
我们的研究表明,COL1A1基因中的单核苷酸多态性与汉族人群中的高度近视无显著关联。
