Mutations that disrupt the glycosylation sequence of rhodopsin (RHO) can cause the autosomal dominant form of retinitis pigmentosa (adRP), a blinding retinal disease characterized by gradual degeneration of rod photoreceptors (Zhu et al., 2004; Sullivan et al., 1993; Murray et al., 2015). This evidence concerns the gene RHO and retinitis pigmentosa.
