Our results were unable to confirm the association of index SNP rs1192415 at TGFBR3-CDC7 loci with VF progression, as reported in the study of Trikha et al. (2015), which showed among the loci of CDKN2B-AS1, SIX1-SIX6, CAV1-CAV2, ABCA1, GAS7, AFAP1, GMDS, PMM2, only TGFBR3-CDC7 (index SNP rs1192415) was associated with VF progression in POAG patients from Singapore. Here, SIX1 is linked to open-angle glaucoma.
