Strain developmentDeveloped by Yoshibumi Matsushima, Saitama Cancer Center. Spontaneous mutation arose in BALB/c and MSM background. The mutant mice were backcrossed to MSM/Ms.
Strain descriptionA animal model for Waardenburg syndrome type 4. Waardenburg syndrome (WS) is a hereditary auditory-pigmentary syndrome with hearing impairment and pigment anomaly, and the WS type 4 is associated with Hirschsprung disease. WS4 mutant mice were spontaneously arose in a breeding colony with BALB/c and MSM mixed background. Homozygous mutant mice show piebald and deafness, and most of them die between 2 and 4 weeks after birth due to megacolon. The results of allelism tests indicated that WS4 is allelic with Ednrb mutant mice (piebald-lethal and JF1).
Colony maintenanceHeterozygote x Wild-type [MSM/Ms]
