About this section
OMIM:49 Autosomal recessive childhood-onset severe retinal dystrophy is a heterogeneous group of disorders affecting rod and... (604393) more...

MalaCards based summary: Leber Congenital Amaurosis 4, also known as leber congenital amaurosis type 4, is related to cone-rod dystrophy x-linked 2 and cone-rod dystrophy, and has symptoms including keratoconus, autosomal recessive inheritance and optic disc pallor. An important gene associated with Leber Congenital Amaurosis 4 is AIPL1 (Aryl Hydrocarbon Receptor Interacting Protein-Like 1), and among its related pathways are The phototransduction cascade and Visual Cycle in Retinal Rods. Affiliated tissues include retina and eye, and related mouse phenotypes are pigmentation and nervous system.

UniProtKB/Swiss-Prot:67 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.
