Summaries for CRYGD Gene

Entrez Gene Summary for CRYGD Gene

  • Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins. Mammalian lens crystallins are divided into alpha, beta, and gamma families; beta and gamma crystallins are also considered as a superfamily. Alpha and beta families are further divided into acidic and basic groups. Seven protein regions exist in crystallins: four homologous motifs, a connecting peptide, and N- and C-terminal extensions. Gamma-crystallins are a homogeneous group of highly symmetrical, monomeric proteins typically lacking connecting peptides and terminal extensions. They are differentially regulated after early development. Four gamma-crystallin genes (gamma-A through gamma-D) and three pseudogenes (gamma-E, gamma-F, gamma-G) are tandemly organized in a genomic segment as a gene cluster. Whether due to aging or mutations in specific genes, gamma-crystallins have been involved in cataract formation. [provided by RefSeq, Jul 2008]

Disorders for CRYGD Gene

(1) OMIM Diseases for CRYGD Gene (123690)


  • Cataract 4, multiple types (CTRCT4) [MIM:115700]: 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. CTRCT4 includes crystalline aculeiform, congenital cerulean and non-nuclear polymorphic cataracts, among others. Crystalline aculeiform cataract is characterized by fiberglass-like or needle-like crystals projecting in different directions, through or close to the axial region of the lens. Non-nuclear polymorphic cataract is a partial opacity with variable location between the fetal nucleus of the lens and the equator. The fetal nucleus is normal. The opacities are irregular and look similar to a bunch of grapes and may be present simultaneously in different lens layers. Congenital cerulean cataract is characterized by peripheral bluish and white opacifications organized in concentric layers with occasional central lesions arranged radially. The opacities are observed in the superficial layers of the fetal nucleus as well as the adult nucleus of the lens. Involvement is usually bilateral. Visual acuity is only mildly reduced in childhood. In adulthood, the opacifications may progress, making lens extraction necessary. Histologically the lesions are described as fusiform cavities between lens fibers which contain a deeply staining granular material. Although the lesions may take on various colors, a dull blue is the most common appearance and is responsible for the designation cerulean cataract. {ECO:0000269 PubMed:10521291, ECO:0000269 PubMed:10915766, ECO:0000269 PubMed:12011157, ECO:0000269 PubMed:12676897, ECO:0000269 PubMed:16943771, ECO:0000269 PubMed:17564961, ECO:0000269 PubMed:21031598, ECO:0000269 PubMed:9927684}.
