Also, we performed the haplotype analysis and identified the haplotypes A-G-C-G-G and G-A-T-A-T of IL-9 SNPs (rs1859430, rs2069870, rs11741137, rs2069885, and rs2069884), which were associated with the decreased odds of early AMD (p = 0.035 and p = 0.015, respectively). Here, IL9 is linked to age-related macular degeneration.
