An important gene associated with Occult Macular Dystrophy is RP1L1 (RP1 Like 1), and among its related pathways/superpathways are Ciliopathies and Visual signal transduction: Cones. Affiliated tissues include retina and eye, and related phenotypes are macular dystrophy and slow decrease in visual acuity
