Strain Information

Image
BRC No.RBRC00422
TypeSpontaneous Mutation
SpeciesMus musculus
Strain nameC.Cg-Cpox<nct>/JmsRbrc
Former Common nameNCT, BALB/c-nct/nct
H-2 Haplotype
ES Cell line
Background strain
Appearancealbino [A/A b/b c/c]
Strain developmentCataract mutation arose spontaneously in the multiple breeding colony. The mutant mice were backcrossed to BALB/c (1988).
Strain descriptionNakano cataract mice, spontaneous recessive mutant. Homozygous mutant mice develop cataracts. A spontaneous G to T transversion was occurred in the Cpox gene, resulting in the amino acid substitution of Leu for Arg at position 380.
Colony maintenanceSibling Mating (Homozyogote x Homozygote)
