pigmentation
• ~10% of adult mice exhibit a white belly spot
• increased ear pigmentation is seen by 3 weeks of age and persists throughout adult life
• adults show excess epidermal pigmentation in the footpads, tail and ears
• excess pigment in a uniform and slanted stripe prominent over the volar pad at the base of the first digit; bluish-gray in color (J:86685)
• increased footpad pigmentation is seen by 3 weeks of age and persists throughout adult life; pigment accumulates in the footpad epidermis (J:139244)
• at P3, P10 and P30, Kitl (kit ligand) mRNA levels are significantly increased in the footpad epidermis relative to control mice (J:139244)
• increased Trp53 staining is noted in the adult footpad epidermis relative to control mice (J:139244)
• dark pigmentation of the tail (J:81301)
• increased tail pigmentation is seen by 3 weeks of age and persists throughout adult life (J:139244)
• pigment accumulates in the adult tail epidermis, whereas the dermis is unaffected (J:139244)

integument

growth/size/body
• increased ear pigmentation is seen by 3 weeks of age and persists throughout adult life
• mice show a ~10-15% reduction in birth weight relative to control mice
• at P21, mice exhibit a significant reduction in body weight on both an inbred (C3HeB/HeJ) and a mixed genetic background

hematopoietic system
