摘要：Background: Primary open-angle glaucoma (POAG) is the most common form of glaucoma with a genetic predisposition. The relationship between polymorphisms in MYOC or APOE promoter region and POAG has been addressed in many case-control studies, but the published results were not consistent. Methods: A meta-analysis assessing the association between five single nucleotide polymorphisms (SNPs) (in MYOC promoter: rs12035719 and rs2075648; in APOE promoter: rs405509, rs769446 and rs449647) and the risk of POAG was performed based on included studies from literature research. In fixed effect model or random effect model, the Mantel-Haenszel (M-H) pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were used to evaluate the genetic association. Stratification analysis was also conducted to test the association within Asian or Caucasian populations. Results: Twenty five case-control studies within multiple populations were identified and no publish bias was observed. Significant association was detected between POAG risk and MYOC rs2075648 in Caucasian (GA+AA vs. GG, OR=0.587, 95% CI=0.437-0.788, P < 0.001). For other SNPs and in other ethnic populations, no statistic evidence was detected for significant association between them and the development of POAG. Conclusions: This meta-analysis suggested a genetic association between one of MYOC polymorphism (rs2075648) and the risk of POAG only in Caucasian population. The significant heterogeneity for this locus might imply the different POAG genetic basis among different populations.
