BRC No.RBRC01262
TypeSpontaneous Mutation
SpeciesMus musculus
Strain nameC3.Cg-Mitf<mi-bw>/Rbrc
Former Common nameBlack-eyed white, Mitf<mi-bw> mutant mouse
H-2 Haplotype
ES Cell line
Background strain
Appearanceblack eyed white [A/A B/B C/C mi<bw>/mi<bw>]
Strain developmentThe original mutant strain, C3HBSt carrying Mitf<mi-bw> allele was provided by Dr. Walter C. Quevedo Jr., Brown University to Tohoku University. The originals were backcrossed to C57BL/6J strain for 13 times. After several years, they were backcrossed to C3H/He strain because the homozygous mice became difficult to breed.
Strain descriptionC3;B6-Mitf<mi-bw>. The Mitf, microphthalmia-associated transcription factor plays a critical role in the development of melanocytes, mast cells, osteoclasts and pigmented epithelium. Homozygous mice for the Mitf<mi-bw> mutation display a white coat with black eyes. In this allele, a L1 element was inserted into intron 3. This strain is useful as an animal model for Waardenburg syndrome type 2 (WS2)
Colony maintenanceSibling Mating (Homozygote x Homozygote)Homozygote shows white coat color with black eyes.
