OMIM:50 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 retinitis pigmentosa, juvenile, 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). Affiliated tissues include retina, and related mouse phenotypes are cardiovascular system and pigmentation.

UniProtKB/Swiss-Prot:68 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.
