Summaries for Cataract 22, Multiple Types

UniProtKB/Swiss-Prot : 73 Cataract 22, 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. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. CTRCT22 includes nuclear cataract among others. Nuclear cataracts affect the central nucleus of the eye, and are often not highly visually significant. The density of the opacities varies greatly from fine dots to a dense, white and chalk-like, central cataract. The condition is usually bilateral. Nuclear cataracts are often combined with opacified cortical fibers encircling the nuclear opacity, which are referred to as cortical riders.

MalaCards based summary : Cataract 22, Multiple Types, is also known as cataract, congenital nuclear, autosomal recessive 2. An important gene associated with Cataract 22, Multiple Types is CRYBB3 (Crystallin Beta B3). The drug Castor has been mentioned in the context of this disorder. Affiliated tissues include eye, and related phenotypes are glaucoma and developmental cataract

Disease Ontology : 12 A cataract that has material basis in heterozygous or homozygous mutation in the beta-B3 crystallin gene (CRYBB3) on chromosome 22q11.

OMIM : 56 Mutations in the CRYBB3 gene have been identified in families with cataract, described as congenital nuclear cataract with cortical riders, nuclear, posterior polar, anterior polar, and cortical. The preferred title/symbol of this entry was formerly 'Cataract, Congenital Nuclear, Autosomal Recessive 2; CATCN2.' (609741)
