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)

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
• mice exhibit a lower red blood cell (RBC) count on both an inbred (C3HeB/HeJ) and a mixed genetic background
• ~5% and ~10% reductions in RBC count are noted at 8 weeks and 20 weeks of age, respectively
• mice show a ~50% reduction in reticulocyte count relative to control mice

cellular
• at 8 weeks of age, mice exhibit an increase in annexin V-positive bone marrow progenitor cells (lineage-cKit+) relative to control mice, indicating increased apoptosis
• however, bone marrow cytology is normal

limbs/digits/tail
• 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)

• pigment accumulates in the adult tail epidermis, whereas the dermis is unaffected (J:139244)

craniofacial
• increased ear pigmentation is seen by 3 weeks of age and persists throughout adult life

hearing/vestibular/ear
• increased ear pigmentation is seen by 3 weeks of age and persists throughout adult life
