Figure 1. DKK1, DKK2, and FOXO1 associations with CCT in Singapore Indian and Malaysian populations. In the Singapore Indian population, variants adjacent to DKK1 (rs1896368; p=1.32×10⁻³; A), DKK2 (rs17510449; p=7.34×10⁻⁴; C), and FOXO1 (rs7326616; p=1.56×10⁻⁴ and rs4943785; p=1.19×10⁻³; E) are associated with central corneal thickness (CCT). In the Singapore Malaysian population, a variant adjacent to DKK2 [rs10015200; p=2.26×10⁻³] (D) is associated with CCT. Variants in the vicinity of DKK1 (B) and FOXO1 (F) are not associated with CCT in the Singapore Malaysian population.
