| Genetic information | O377 was identified as a new dominant cataract mutation in mice after radiation experiments. The mutation was mapped to chromosome 5 and characterized as an A to T substitution at the end of intron 5 of the Crybb2 gene. It led to alternative splicing with a 57-bp insertion in the mRNA and to 19 additional amino acids in the protein. Disclaimer - Special restrictions: 1) Mutant development was phenotype driven. Although for some mutant lines, linkage data and the molecular characterization of the causative mutation has been published, EMMA has not genotyped the strains and can not provide genotyping protocols. 2) Some lines showed low penetrance of the phenotype. 3) Only sperm available. Rederivation service can not be offered. 4) EMMA quality control standards may not apply for these strains. 5) EMMA has not verified the breeding performance and the genetic background of the strains. The genotype/phenotype of the mice is not confirmed by INFRAFRONTIER/EMMA. We strongly recommend that the recipient confirms genotype/phenotype upon receipt. |
| Phenotypic information | Homozygous:Progressive dominant cataract, altered sensorimotor gating, decreased number of parvalbumin-positive interneurons in the hippocampus, increased translation of input-to-output neuronal activity in the dentate gyrus, reduced number of dendrites and dendritic branches, alterations in the parvalbumin-positive cell number in the thalamic reticular nucleus.Heterozygous:Progressive dominant cataract |
| Breeding history | The original mutant, expressing progressive cataract, was recovered in the offspring of male mice exposed to 3 Gy X-ray irradiation. The presumed mutation was genetically confirmed and crossed to strain C3H/El and kept by brother x sister breeding. |
