• N: normal phenotype

limbs/digits/tail

abnormal autopod morphology ( J:210836 )

• mice develop palmoplantar keratoderma by 6 weeks of age

• however, no inflammatory infiltrates are seen

integument

increased keratinocyte proliferation ( J:210836 )

• BrdU incorporation into keratinocytes of paw skin is increased

impaired skin barrier function ( J:210836 )

• water loss from the paw skin is greater than in wild-type mice, but water loss from the skin on the ear and back is similar to wild-type mice

abnormal stratum corneum lipid matrix formation ( J:210836 )

• stratum corneum of the paw contains abundant lipid droplets

abnormal epidermis stratum granulosum morphology ( J:210836 )

• stratum granulosum of the paw is poorly demarcated

thick epidermis ( J:210836 )

• epidermis of the paw is thickened

• however, skin and hair are normal
