♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
integument
impaired skin barrier function ( J:204137 )
• compromised epidermal barrier function at postnatal day 21
greasy coat ( J:204137 )
• greasy and tousled appearance identical to that in homozygous germ line null mice

adipose tissue
abnormal white adipose tissue physiology ( J:204137 )
• elevated lypolysis in isolated inguinal WAT

homeostasis/metabolism
impaired skin barrier function ( J:204137 )
• compromised epidermal barrier function at postnatal day 21
increased liver cholesterol level ( J:204137 )
• greater accumulation of cholesteryl esters at P21
• accumulation is less than in homozygous germ line null mice

liver/biliary system
increased liver cholesterol level ( J:204137 )
• greater accumulation of cholesteryl esters at P21
• accumulation is less than in homozygous germ line null mice
abnormal liver physiology ( J:204137 )
• expression analysis in fostered pups indicates a defect in liver adaptation to weaning
