Ocular expression of TSPAN10 has been identified in the iris, ciliary body and retinal pigment epithelium (Wistow et al. 2002) and this locus has previously demonstrated genome-wide significant association with eye colour, myopia and age-related macular degeneration (Pickrell et al. 2016; Fritsche et al. 2016; Liu et al. 2010). Here, TSPAN10 is linked to myopia.
