Genotype A/A B/B C/C mi/mi  
Strain development The 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 description C3;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 maintenance Sibling Mating (Homozygote x Homozygote)
Homozygote shows white coat color with black eyes.
