Summaries for Cataract 2, Multiple Types

UniProtKB/Swiss-Prot : 73 Cataract 2, multiple types: An opacification of the crystalline lens of the eye that frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. CTRCT2 includes Coppock-like cataract, among others. Coppock-like cataract is a congenital pulverulent disk-like opacity involving the embryonic nucleus with many tiny white dots in the lamellar portion of the lens. It is usually bilateral and dominantly inherited. In some cases, CTRCT2 is associated with microcornea without any other systemic anomaly or dysmorphism. Microcornea is defined by a corneal diameter inferior to 10 mm in both meridians in an otherwise normal eye.

MalaCards based summary : Cataract 2, Multiple Types, also known as cataract, coppock-like, is related to cataract 30, multiple types and cataract 30. An important gene associated with Cataract 2, Multiple Types is CRYGC (Crystallin Gamma C). Affiliated tissues include eye, and related phenotypes are photophobia and microcornea

Disease Ontology : 12 A cataract that has material basis in heterozygous mutation in the CRYGC gene on chromosome 2q33.

OMIM : 56 Mutations in the CRYGC gene have been found to cause several types of cataract, which have been described as Coppock-like; embryonic, fetal, infantile nuclear; zonular pulverulent; and lamellar. Some patients also exhibit microcornea. Before it was known that mutations in the CRYGC gene cause several types of cataract, this entry was titled 'Cataract, Coppock-like,' with the symbol CCL.
