phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• all mice die within 8 hours of birth

integument
• 14.8 times higher trans-epidermal water loss in newborn mice compared with heterozygotes
• slightly more layers than in control mice
• thicker than in control cells
• impaired (thin) lipid lamella formation with small, immature, granular lamellar bodies
• at E18.5
• at E18.5
• at E18.5

growth/size/body
• rapid weight loss after birth due to trans-epidermal water loss

homeostasis/metabolism
• 14.8 times higher trans-epidermal water loss in newborn mice compared with heterozygotes
• almost complete loss of acylceramide and its precursor omega-hydroxy ceramide in the epidermis of E18.5 mice
• however, other lipid levels are normal

embryo
• persistent on the outer most layer of epidermis
