Mouse lines carrying:
Kittm1Ber mutation (0 available); any Kit mutation (182 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
pigmentation
• in regions where the coat was white, melanin pigment was absent from the hair shafts and melanocytes were absent from the hair bulbs
• observed in 10% to 15% of mice
• >90% of the body surface area white except around the ear

digestive/alimentary system
N
• neither stomach or intestinal distension were observed as was in Kittm3Ber/tm3Ber mice

hematopoietic system
• reduced number of mast cells in the peritoneal cavity, and the stomach
• normal number of mast cell precursor cells and it was possible to derive mast cells from the bone marrow

immune system
N
• splenomegaly was not observed, as it was in Kittm3Ber/tm3Ber mice
• reduced number of mast cells in the peritoneal cavity, and the stomach
• normal number of mast cell precursor cells and it was possible to derive mast cells from the bone marrow

reproductive system
N
• mice were fully fertile

integument
• in regions where the coat was white, melanin pigment was absent from the hair shafts and melanocytes were absent from the hair bulbs
• observed in 10% to 15% of mice
• >90% of the body surface area white except around the ear
