The tremendous heterogeneity makes the genetics of RP complex, however, the pathogenesis has been linked to disease‐causing variants in Mer tyrosine kinase (MERTK), a gene that encodes a receptor of the Tyro3/Axl/Mer family of tyrosine kinases; and retinoid isomerohydrolase (RPE65), a gene that encodes a protein involved in visual transduction post‐light exposure.55 This evidence concerns the gene RPE65 and retinitis pigmentosa 1.
