This is reasonable when we correlate the clinical phenotypes; CEP290 is related to LCA, RP1L1 is related to occult macular dystrophy (OMD), ABCA4 is related to Stargardt disease and severe forms of autosomal recessive RP, and CYP4V2 is related to BCD. Here, CYP4V2 is linked to occult macular dystrophy.
