Any other 5 candidates involved in phototransduction pathways were not well-studied in other eye diseases, such as PRKACB, RGS9BP, GRK1, PRKAR1A, and RCVRN. Interestingly, another well-established pathway involved in myopia, ‘dopamine receptor signaling’ was also found in this study. This evidence concerns the gene RGS9BP and myopia.
