The study did not detect any direct link between genotype/allele frequency of rs1900004 in ATOH7 and POAG or its related clinical indices such as IOP and cup/disc ratio indicating that this polymorphism is not a risk factor for POAG in a Saudi cohort.
The rs1063192 (CDKN2B) and rs1900004 (ATOH7) seem to be non-IOP-related genetic risk factors for NTG, and the rs1547014 (CHEK2) is a genetic risk factor for HTG.
