phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• by weaning, only about 27% of expected numbers are still alive
• only about 71% of expected numbers of homozygotes are still alive at E11.5

growth/size/body
• smaller than controls during suckling period although normal in size from E11.5 to birth
• after 6 weeks of age, weight gain is normal and mice attain normal size
• 2-3 days before death, mice begin to display a wasted phenotype, appear malnourished, lethargic, watery diarrhea

behavior/neurological
• beginning 2-3 days before death

digestive/alimentary system
• reduced numbers of goblet cells producing sialomucin
• watery diarrhea in mice that die starting 2-3 days before death
• intestinal endothelium fails to transform from pseudostratified to columnar by E17.5
• formation of villi is delayed and those present are misshapen
• connective tissue under the lamina propria of the villi is disorganized
• absorptive enterocytes are morphologically abnormal
• tightly packed with apical cytoplasmic snouts
• microvilli are short
• increased numbers of mitochondria and ribosomes

cellular
• reduced numbers of goblet cells producing sialomucin
