Retinitis pigmentosa-86 (RP86) is characterized by night blindness followed by progressive narrowing of visual fields and decline in visual acuity, with typical findings of RP on fundus examination, including attenuated retinal vessels, waxy pallor of the optic disc, and bone spicule-like pigmentation (de Bruijn et al., 2018). For a general phenotypic description and a discussion of genetic heterogeneity of retinitis pigmentosa, see 268000.

Retinitis pigmentosa-89 (RP89) is characterized by classic features of RP as well as features of ciliopathy, including postaxial polydactyly and renal and hepatic disease. Onset of symptoms is within the first decade of life (Cogne et al., 2020). For a general phenotypic description and discussion of genetic heterogeneity of RP, see 268000.

Retinitis pigmentosa-90 (RP90) is characterized by early-onset night blindness, within the first decade of life. Patients exhibit other typical features of RP, including retinal vessel attenuation, optic disc pallor, and retinal pigment epithelium (RPE) atrophy and pigmentation abnormalities. Macular pseudocoloboma and cystoid macular edema have also been observed (Pierrache et al., 2017). For a discussion of genetic heterogeneity of RP, see 268000.
