Symbol: CrygbNop
Name: crystallin, gamma B; nuclear opacity
MGI ID: MGI:1857597
Synonyms: Cat2no, CrygbCat2-nop, Nop
Gene: Crygb  Location: Chr1:65080219-65082288 bp, - strand  Genetic Position: Chr1, 32.82 cM
Strain of Origin:  (101/El x C3H/El)F1
Allele Type:    Spontaneous
Mutations:    Insertion, Intragenic deletion
Mutation detailsAn 11 bp deletion combined with a 4 bp insertion in exon 3 of Crygb causes a frameshift at codon 139 that leads to premature termination at codon 145 and produces a truncated gene product. (J:50319)
Inheritance:    Dominant

Both homozygotes and heterozygotes are fully viable and fertile, and penetrance is complete in both. The nuclear opacity is seen as a white spot in the eye. The cataractous lens shows decreased activity of four glycolytic enzymes, a decreased amount of glutathione disulfide, and loss of a single protein, probably a gamma-crystallin, as revealed by isoelectric focusing (J:7589, J:23992).
