ABCA4 mutations can result in multiple vision related phenotypes (Cideciyan et al., 2009; Klevering et al., 2004; Shroyer et al., 1999; Valverde et al., 2007) including Retinitis pigmentosa, Fundus flavimaculatus, Cone-rod dystrophy, and Stargardt disease (Lin et al., 2016), which is characterized by juvenile macular degeneration. This evidence concerns the gene ABCA4 and Cone rod dystrophy.
