CEP290 and Leber congenital amaurosis: A review of the literature identified 177 unique LCA causing mutations in eight different genes: aryl hydrocarbon receptor interacting protein-like 1 (AIPL1), crumbs homolog 1 (CRB1), cone-rod homeobox (CRX), guanylate cyclase 2D (GUCY2D), nephronophthisis 6 (NPHP6), retinol dehydrogenase 12 (RDH12), retinal pigment epithelium-specific protein 65 kDa (RPE65), and retinitis pigmentosa GTPase regulator interacting protein 1 (RPGRIP1).
