PRPH2 retinopathy exhibits significant phenotypic variability, and the associated phenotypes include adult vitelliform macular dystrophy (AVMD: OMIM 608161), pattern dystrophy (PD OMIM: 169150), including butterfly-shaped pattern dystrophy, central areolar choroidal dystrophy (CACD: OMIM 613105), pseudo-Stargardt pattern dystrophy (PSPD: OMIM 169150), and retinitis pigmentosa (RP: OMIM 608133) [3,13,34,35,38,39,40,41]. The gene discussed is PRPH2; the disease is retinal disorder.
