Gyrate Atrophy of Choroid and Retina, also known as ornithine aminotransferase deficiency, is related to macular retinal edema and ornithinemia. An important gene associated with Gyrate Atrophy of Choroid and Retina is OAT (Ornithine Aminotransferase), and among its related pathways/superpathways are Visual phototransduction and Visual Cycle in Retinal Rods. The drugs Ornithine and Arginine have been mentioned in the context of this disorder. Affiliated tissues include retina and eye, and related phenotypes are progressive visual loss and myopia
