|
• vibrissa hair fiber thickness and length are reduced
|
• interfollicular epithelium is hyperpigmented
|
• foot skin epithelium is hyperkeratotic

• periorbital area shows normal eyelashes but pelage hair numbers are reduced and hair pattern is disrupted
|
• periorbital area shows normal eyelashes but pelage hair numbers are reduced and hair pattern is disrupted
|
• epithelial cyst-like structures on the dorsal skin of adults
|
• at 6 months of age
|
• lipid-retaining cells are increased in sebaceous glands
|
• Meibomian glands are hyperplastic
|
• epithelial cyst-like structures on the dorsal skin of adults
|
• characteristic hair types are replaced by abnormally pigmented, shorter, thinner hairs with misshaped and twisted medulla structures
|
• extensive alopecia on the dorsal skin of adults
• alopecia appears during the first hair cycle and does not progress to open lesions, ulcers, or scarring
|
• ingrown hair fibers
|
• hair medulla is abnormal with misaligned air cells
|
• affected follicles of mutants have only one hair type that resembles abnormal zigzag hair
|
• paws exhibit supernumerary claws that form on the lateral sides of digits
• claw dystrophies include unique outgrowths of the hyponychium that extends beyond the claw matrix
• supernumerary claw matrices are covered with compact keratin structures extending from the proximal claw fold
|
• pigmentation is increased in the claws
• hyperpigmentation is due to the presence of ectopic pigmented melanocytes in the dermal-epidermal junction in the claw matrix
|
• presence of ectopic pigmented melanocytes in the dermal-epidermal junction in the claw matrix
|
• hair follicle dystrophy on the dorsal skin of adults; prevalence is similar at 3 and 6 months of age
• skin and hair appear normal at P9, however dystrophic hair follicle cysts begin to form by 3 weeks of age and become prevalent by 3 months
• dystrophic follicle cysts form from hair follicle progenitor cells that fail to differentiate properly
• coiled hair follicles
• lipid-retaining cells are increased in tail hair follicles
|
• dystrophic follicle cysts form from hair follicle progenitor cells that fail to differentiate properly
|
• dilated infundibulae on the dorsal skin of adults
• enlarged infundibula of dystrophic follicles sometimes contains keratin arranged in columns resembling a hair shaft and others that contain keratin with less structure
|
• hair follicle orientation is abnormal, with fibers pointing towards the dermis instead of the epithelium
|
• disrupted hair follicle alignment
|
• vibrissa hair fiber thickness and length are reduced
|
• interfollicular epithelium is hyperpigmented
|
• apoptosis is increased in the epidermal basal layer of the interfollicular skin at 6 months of age
|
• hyperkeratosis is seen at 6 months of age
• foot skin epithelium is hyperkeratotic
|
• dystrophic follicular epithelium is often stratified without a significant granular layer
|
• keratinocytes in all layers are variable in cell size and shape
|
• marker analysis indicates that hair differentiation is disrupted in KRT14-producing keratinocytes, however epidermal differentiation is maintained but control of homeostasis is disrupted
|
• moderate epidermal hyperplasia is seen at 6 months of age
• hyperplastic epidermis in the tail skin
|
• pigmentation is increased in the foot pads and feet
|
• tail skin shows a nonautonomous increase of pigment cells
• increase in number of melanoblasts in the interscale region of the tail
|
• marker analysis indicates that hair differentiation is disrupted in KRT14-producing keratinocytes, however epidermal differentiation is maintained but control of homeostasis is disrupted
|
• lipid-retaining cells are increased in sebaceous glands
|
• Meibomian glands are hyperplastic
|
• pigmentation is increased in the foot pads and feet
|
• the tail skin exhibits hyperkeratosis, hyperpigmentation, a reduction in normal hair, and an increase of lipid retaining cells
|
• tail skin shows a nonautonomous increase of pigment cells
• increase in number of melanoblasts in the interscale region of the tail
|
• pigmentation is increased in the foot pads and feet
|
• tail skin shows a nonautonomous increase of pigment cells
• increase in number of melanoblasts in the interscale region of the tail
|
• hyperpigmentation is due to the presence of ectopic pigmented melanocytes in the dermal-epidermal junction in the claw matrix
|
• enlarged eyelids
|
