A common genetic variant as an effect modifier for primary angle closure glaucoma.

Background: Epidemiological studies provide evidence of a genetic basis for primary angle closure glaucoma (PACG), and genome-wide association studies (GWAS) have identified various candidate genes as susceptibility loci. However, different results produced by previous studies make the role of a common genetic variant in the COL11A1 gene (rs3753841) remains elusive. Thus, we carried out a meta-analysis, attempting to determine the association of rs3753841 with PACG.
