increased body weight ( J:113730 )
• mice display significantly higher body weight than wild-type littermates (females at week 11 are 138% of wild-type, at week 18 - 147%; males week 11- 116% at week 18, 123% of wild-type)
obese ( J:113730 )
increased susceptibility to weight gain ( J:113730 )
• observed weight gain is significantly greater than wild-type between 5 and 20 weeks of age; more pronounced in females than males
