endocrine/exocrine glands
• secretory cells contain large lipid droplets which may break through holes in the apical surface filling the luminal spaces
• lactation is compromised with only 50 - 60% of pups surviving to weaning
• milk contains 25-35% (wt/vol) lipid a 50% increase compared to wild-type mice
• many large lipid droplets are seen in the milk from homozygous mutants
