Genes associated with IRDs and high myopia clustered into functional categories that included collagen/structural integrity (COL2A1, COL9A1, COL11A1, COL18A1, P3H2), phototransduction and visual cycle (PDE6C, PDE6H, GUCY2D, ARR3, RBP3), ciliary trafficking and microtubule-associated genes (RPGR, RP2, IFT140, CFAP418, FAM161A), synaptic ribbon and bipolar cell signaling (NYX, CACNA1F, TRPM1, GRM6, LRIT3, GPR179), opsin-related genes (OPN1LW, OPN1MW), and miscellaneous categories (VPS13B, ADAMTS18, LAMA1). This evidence concerns the gene GPR179 and myopia.
