GUCY2D is a gene that encodes the protein guanylate cyclase 2D, which plays a crucial role in the phototransduction pathway of the retina. Mutations in this gene are associated with various forms of inherited retinal diseases, such as Leber congenital amaurosis (LCA) and cone-rod dystrophy (CORD). Understanding its function and the mutations that occur can provide insights into the epidemiology of these diseases.
