phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• appear normal for 4-6 days after birth
• mice die within 2 days of the onset of respiratory distress which occurs around day 6-12
• survival can be prolonged by draining fluid in thorax but only to about 21 days of age

growth/size/body
• smaller than littermate controls by day 6-8

respiratory system
• high concentrations of both triglycerides and cholesterol
• 90% of cells in fluid collected in the thoracic cavity were lymphocytes
• all mice show signs of respiratory distress between 6 and 12 days of age

immune system
• edema and lymphocytes sometimes seen in tissue surrounding thoracic duct

cardiovascular system
• edema and lymphocytes sometimes seen in tissue surrounding thoracic duct

homeostasis/metabolism
• high concentrations of both triglycerides and cholesterol
• 90% of cells in fluid collected in the thoracic cavity were lymphocytes
