GLB1L3 and Leber congenital amaurosis: In this study, we investigated the expression of the gene encoding β-galactosidase (Glb)-1-like protein 3 (Glb1l3), a member of the glycosyl hydrolase 35 family, during retinal degeneration in the retinal pigment epithelium (RPE)-specific 65-kDa protein knockout (Rpe65−/−) mouse model of Leber congenital amaurosis (LCA).
