phenotype observed in females
phenotype observed in males
N normal phenotype
adipose tissue
• mutants exhibit an accumulation of adipose mass, including an increase in visceral and subcutaneous fat compartments

behavior/neurological
• fasted and refed mutants display deficient postprandial satiation
• mutants are hyperphagic, independent of sex, dietary nutrients, or dietary caloric content
• however, mutants exhibit normal lipid digestion, lipid absorption, distribution and clearance, normal energy mobilization and expenditure, normal circadian cycles and thermoregulatory reflexes to cold, indicating that an increase in caloric consumption is the probable cause of the excess adiposity

cardiovascular system
• mean heart size in mice raised on either the low calorie or high calorie diet is increased compared to wild-type mice

growth/size/body
• mutants raised on a standard low calorie diet, moderate calorie diet, or high calorie diet exhibit an increased body weight compared to wild-type mice
• females raised on the high calorie diet showed the highest weight increase, with mutants being 26.3% heavier than wild-type mice

homeostasis/metabolism
• fasted serum concentrations of 12 months old mutants raised on a high caloric diet are increased compared to wild-type mice on the same diet
• fasted serum leptin levels are increased at 10-12 and 18 months of age in mutants raised on either the low calorie or high calorie diet
• impaired glycemic control
• mice raised on a low calorie diet exhibit increased hepatic triglyceride content

integument

liver/biliary system
• mice raised on a low calorie diet exhibit increased hepatic triglyceride content
