mortality/aging
• lethality occurs within 24 hours of birth

homeostasis/metabolism
• at E27.5 and 18.5, mice were dissected and weighed every hour for 6 hours; mutants lose between 21 and 27% of their body weight
• skin of newborns dessicates rapidly; at E17.5 and E18.5, fetuses do not display barrier acquisition

integument
• skin of newborns dessicates rapidly; at E17.5 and E18.5, fetuses do not display barrier acquisition
• epidermis has thickened compressed stratum corneum
• skin of newborn mice rapidly dessicates and appears scaly
• affected mutants have red skin
• skin appears scaly after moisture loss
• mice are born with shiny skin
