Mutations in RLBP1 have been associated with a group of autosomal recessive retinal diseases comprising autosomal recessive retinitis pigmentosa (Maw et al., 1997), Bothnia dystrophy (Burstedt et al., 1999), Newfoundland rod–cone dystrophy (Eichers et al., 2002), retinitis punctata albescens (RPA) (Morimura et al., 1999), and fundus albipunctatus (Katsanis et al., 2001). This evidence concerns the gene RLBP1 and retinitis punctata albescens.
