Summary: This gene encodes a member of the beta/gamma-crystallin family of proteins. Crystallins constitute the major proteins of vertebrate eye lens and maintain the transparency and refractive index of the lens. This gene and several family members are present in a gene cluster on chromosome 2. Mutations in this gene have been shown to cause multiple types of cataract, including Coppock-like cataract and zonular pulverulent cataract, among others. [provided by RefSeq, Jan 2015]

Title: [Identification of a novel CRYGC mutation in a pedigree affected with congenital cataracts].
Study identified eight different mutations in CRYGC associated with autosomal dominant congenital nuclear cataracts (ADCC) in a cohort of Chinese family and shows that CRYGC mutations are responsible for 4.1% of ADCC families in the cohort. The results expand the spectrum of CRYGC mutations as well as their associated phenotypes.
Title: Novel mutations in CRYGC are associated with congenital cataracts in Chinese families.
We examined a cohort of Chinese patients with congenital cataracts and studied the phenotypes and genotypes. Extralenticular abnormalities, such as microcornea and ocular coloboma, can also be found in patients with congenital cataracts. The phenotype of congenital cataracts associated with macular and optic disc coloboma was reported for the first time in this study.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
