Summaries for Leber Congenital Amaurosis 8

About this section
OMIM:52 Leber congenital amaurosis comprises a group of early-onset childhood retinal dystrophies characterized by vision loss,... (613835) more...

MalaCards based summary: Leber Congenital Amaurosis 8, also known as LCA8, is related to leber congenital amaurosis 1 and liver cirrhosis, and has symptoms including visual impairment, cataract and undetectable electroretinogram. An important gene associated with Leber Congenital Amaurosis 8 is CRB1 (Crumbs 1, Cell Polarity Complex Component), and among its related pathways are Notch Signaling Pathway (sino) and Tight junction. Affiliated tissues include retina and eye, and related mouse phenotype vision/eye.

Disease Ontology:11 A Leber congenital amaurosis that is characterized by night blindness and thick unlaminated retinas and has material basis in mutation in the CRB1 gene on chromosome 1q31-q32.

UniProtKB/Swiss-Prot:70 Leber congenital amaurosis 8: 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.
