“…Tis suggests that the genetic susceptibility to high myopia among college students in Zhejiang is not signifcantly associated with the rs939658 and rs4778879 loci of the RASGRF1 gene, while the rs8033417 locus may be a risk gene for high myopia among college students in this region while carrying the C allele, and college students carrying the C allele have an increased risk of myopia. However, no evidence was found in the study of Fernandez-Medarde and Santos [19] to support the association of high myopia with the rs8033417 locus of the RASGRF1 gene, and analysis of the reasons for this may be related to the diferent single nucleotide polymorphism loci selected in this study, and diferences in the inclusion criteria for high myopia can also cause changes in gene frequency [20]. Te study of SNPs and genetic susceptibility of specifc myopia groups is important for understanding the molecular genetic mechanisms underlying the development of high myopia in diferent populations in various regions.…”

Objective. The aim of the study is to analyze the correlation between high myopia susceptibility and Ras protein-specific guanine nucleotide-releasing factor-1(RASGRF1) gene polymorphism among college students in Zhejiang. Methods. A stratified whole-group sampling method was used to select 218 cases of college students in Zhejiang who met the inclusion and exclusion criteria from January, 2019, to December, 2021, and they were divided into 77 cases (154 eyes) in the high myopia group and 141 cases (282 eyes) in the medium-low myopia group according to the degree of myopia, and 109 cases of college volunteers without myopia from the same period of medical examination in the region were included in the control group. The single nucleotide polymorphisms (SNPs) located in functional regions were selected by searching the literature and genetic databases, and the base sequences of rs939658, rs4778879, and rs8033417 loci were obtained by genotyping candidate SNPs using multiplex ligase detection reaction technique. The cardinality test was used to compare the differences in genotype frequency distribution of each locus of the RASGRF1 gene between the high myopia group and the low to moderate myopia group and the control group. Results. The genotype frequencies and allele frequencies of the RASGRF1 gene rs939658 locus in the high myopia group compared with the moderate-low myopia group and the control group were not statistically significant P > 0.05 . The genotype frequencies and allele frequencies of the rs4778879 locus of the RASGRF1 gene were compared among the three groups, and the differences were not statistically significant P > 0.05 . The genotype frequency and allele frequency of the rs8033417 locus of the RASGRF1 gene differed significantly among the three groups P < 0.05 . Conclusion. The polymorphism of the rs8033417 locus of the RASGRF1 gene was significantly correlated with the susceptibility of high myopia among college students in Zhejiang.
