Tyrc-p mutation (1 available); any Tyr mutation (382 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
pigmentation
abnormal hair follicle melanogenesis ( J:6611 , J:13319 )
• the amount of melanin found in anagen hairbulbs is reduced by more than 20-fold compared to wild-type mice (J:6611)
• affected mice fail to produce a tyrsoinase isoform with a carboxy-terminal PEP7 epitope, which participates in a high molecular weight complex important to melanogenesis (J:13319)
diluted coat color ( J:6611 )
• mice have slight pigmentation of the coat

integument
