The retinal phenotype of BBS1 is typically described as RP-like rod-cone dystrophy (Grudzinska Pechhacker et al., 2021); however, BBS10 may occur as a cone-rod dystrophy, or even an isolated cone dystrophy (Grudzinska Pechhacker et al., 2021). This evidence concerns the gene BBS1 and retinitis pigmentosa 1.
