Table 1 shows the minor allele frequency (MAF) distribution of rs2472493 and rs7636836 according to glaucoma types and gender in cases and controls. No significant deviation from HWE was observed (p > 0.05). Overall, the MAFs of both the polymorphisms showed no significant association with PACG and PXG. However, rs7636836 [T] variant in FNDC3B was significantly associated with increased risk of PXG among men (OR = 2.69, 95% CI = 1.11–6.51, p = 0.029). No such gender-specific association was observed for rs2472493 in ABCA1. Here, FNDC3B is linked to glaucoma.
