MalaCards based summary: Leber Congenital Amaurosis 4, also known as lca4, is related to leber congenital amaurosis and cone-rod dystrophy, and has symptoms including keratoconus, optic disc pallor and cone/cone-rod dystrophy. An important gene associated with Leber Congenital Amaurosis 4 is AIPL1 (Aryl Hydrocarbon Receptor Interacting Protein Like 1), and among its related pathways are Phototransduction and Visual Cycle in Retinal Rods. Affiliated tissues include retina, bone and eye, and related mouse phenotypes are pigmentation and nervous system.

Disease Ontology:11 A Leber congenital amaurosis that is characterized by a relatively severe phenotype, with maculopathy and marked bone-spicule pigmentary retinopathy in most and keratoconus and cataract in a large subset and has material basis in mutation in the AIPL1 gene on chromosome 17p13.

UniProtKB/Swiss-Prot:69 Leber congenital amaurosis 4: A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus.
