mortality/aging
• mice die within hours of birth

respiratory system
• alveolar spaces are smaller than in wild-type mice
• type II cells lack lamellar body-like organelles
• mice produce less Sftpb protein than in wild-type mice
• mice exhibit alveolar collapse

homeostasis/metabolism
• at E18.5 and birth mice exhibit increased dehydration compared to wild-type mice
• at E18.5, mice exhibit increased skin permeability and higher trans-epidermal water loss compared to wild-type mice

craniofacial
• at birth, some mice exhibit eversions of the lips

growth/size/body
• at birth, some mice exhibit eversions of the lips
• decreased body weight at birth

integument
• at E18.5, mice exhibit increased skin permeability and higher trans-epidermal water loss compared to wild-type mice
• mice exhibit lipid droplets in the upper epidermis
• mice exhibit thick, compact stratum corneum without the normal basket-weave appearance observed in wild-type mice
• mice exhibit numerous defective lamellar granules
• at birth
• at birth
• at E18.5
• at birth, some mice exhibit skin fissures
• at E18.5
• at birth, skin is less flexible than in wild-type mice
• skin development is normal until E15.5 but by E18.5 mice exhibit taut and shiny skin without normal skin folds and exhibit contractures of the limbs
