N normal phenotype
mortality/aging
• incomplete penetrance; significant perinatal losses of heterozygous females
• incomplete penetrance; significant postnatal losses of heterozygous females

growth/size/body

limbs/digits/tail
• feet are sometimes shorter than controls
• other skeletal elements may be affected
• hind toes are often shortened
• one or more hind toes are bent

skeleton
• premature calcification of the vertebral bones and epiphysis of the limb bones is seen at 5 days of age

vision/eye
• both unilateral and bilateral cataracts are seen

behavior/neurological
• offspring of heterozygous females show reduced viability regardless of genotype, suggesting a maternal nurturing defect

pigmentation
• appearance of dark stripes on coat adjacent to bare skin due to visibility of the dark base of hairs

integument
• appearance of dark stripes on coat adjacent to bare skin due to visibility of the dark base of hairs
• at P5, patches of bare skin are apparent among emerging coat hair (J:5403)
• large bare patches are apparent in adults (J:5403)
• bare patches in coat in a linear and blotchy pattern (J:7012)
• adult animals appear scruffy (J:5403)
(J:7012)
• shafts are of uneven diameter and appear twisted
• by P8, mice exhibit hyperkeratotic skin eruptions, arranged in a linear and blotchy pattern
• thick hyperkeratosis; reaches into the hair follicles
