Abstract | PURPOSE: MATERIALS AND METHODS: A total of 869 patients with HM and 804 controls were recruited for this study. The genotyping of five SNPs in COL11A1 and COL18A1 was performed using the SNaPshot method. The genotyping data were analyzed using the χ2 test, and the linkage disequilibrium block structure was calculated and examined by Haploview software. RESULTS: No statistically significant differences (p > 0.05) were identified between HM cases and controls after a Bonferroni correction for multiple tests in the allele frequencies of COL11A1 and COL18A1 SNPs. However, the G allele of rs2236475 showed a susceptible effect for HM (p = 0.016, corrected p = 0.08, odds ratio [OR] = 1.26). Moreover, the carriers of rs2236475GG genotype displayed an increased risk of HM compared with the rs2236475AA and rs2236475AG+AA genotypes (p = 0.008, OR = 1.79, confidence interval [95% CI] = 1.18-2.64, uncorrected; p = 0.012, OR = 1.74, 95% CI = 1.12-2.57, corrected, respectively). CONCLUSIONS: Our results suggested that common polymorphisms in these two candidate genes were unlikely to play major roles in the genetic susceptibility to HM. Nevertheless, to avoid filtering real myopia genes, the role of COL11A1 and COL18A1 in the pathogenesis of myopia requires more refinement in both animal models and human genetic epidemiological studies.
