mortality/aging

neonatal lethality, complete penetrance ( J:119554 )

integument

impaired skin barrier function ( J:119554 )

• skin of newborns dessicates rapidly; at E17.5 and E18.5, fetuses do not display barrier acquisition

• epidermis has thickened compressed stratum corneum

dry skin ( J:119554 )

• skin of newborn mice rapidly dessicates and appears scaly

reddish skin ( J:119554 )

• affected mutants have red skin

scaly skin ( J:119554 )
