ABCA4 and Leber congenital amaurosis: These include Stargardt disease type 1 (caused by mutations in ABCA4) [4,6], AMD—the leading cause of irreversible blindness in older adults, retinitis pigmentosa (RP), and Leber congenital amaurosis (LCA) (associated with mutations in LRAT, RPE65, and RDHs) [7], as well as fundus albipunctatus (FA) (linked to RDH5 and RLBP1 mutations) [8].
