PROM1-related retinopathies can manifest as pan-retinal phenotypes, as in Retinitis Pigmentosa type 41 (RP type 41, OMIM 268000) and Cone-Rod Dystrophy (CORD, OMIM 604116 or 120,970); or as macular dystrophies such as Stargardt's disease type 4 (STGD4, OMIM 248200) [22, 23]. The gene discussed is PROM1; the disease is cone-rod dystrophy.
