phenotype observed in females
phenotype observed in males
N normal phenotype
growth/size/body
• keratin cyst formation is observed
• generalized growth retardation is observed compared to controls

neoplasm
• mice develop spontaneous cutaneous SCC lesions, as well as dysplastic precursor lesions

limbs/digits/tail
• with aging, hyperkeratinization of tail is seen

integument
• aberrant hair follicle cycling occurs
• starting at 2-3 weeks, mice display hair and whisker loss; diffuse alopecia is observed
• at 10 months of age, alopecia has progressed almost to completion
• hypoplastic dermis with increased cellularity is observed
• by 6 months of age, most mice develop hyperkeratotic cutaneous nodules, with all mutants exhibiting multiple lesions by 10 months of age
• examination of some nodules reveals papillomas or inflamed infundibular cyts
• keratin cyst formation is observed
• cutaneous nodules show hyperproliferative keratinocytic lesions exhibiting cellular atypia and an invasive growth pattern
