♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

homeostasis/metabolism

decreased susceptibility to diet-induced obesity ( J:279071 )

• maintain a lean phenotype on a high fat diet

decreased fasting circulating glucose level ( J:279071 )

• after an 18h fast

• however, fed glucose levels are similar to controls

decreased body temperature ( J:279071 )

• drastically reduced after 18 hr of fasting but returns to normal after refeeding

• slightly lower body temperature in response to a cold environment but do adjust body temperature in response to a cold environment

decreased oxygen consumption ( J:279071 )

• during the dark phase

increased insulin sensitivity ( J:279071 )

• after 11 and 12 weeks on a high fat diet

adipose tissue

decreased white adipose tissue amount ( J:279071 )

• on normal chow and a high fat diet

behavior/neurological

decreased food intake ( J:279071 )

• on a high fat diet

growth/size/body

decreased body weight ( J:279071 )

decreased susceptibility to diet-induced obesity ( J:279071 )

• maintain a lean phenotype on a high fat diet

homeostasis/metabolism

decreased susceptibility to diet-induced obesity ( J:279071 )

• maintain a lean phenotype on a high fat diet

decreased body temperature ( J:279071 )

• reduced after 18 hr of fasting but returns to normal after refeeding

• decrease in body temperature induced by fasting is less than in Impact single homozygous mice

growth/size/body

decreased susceptibility to diet-induced obesity ( J:279071 )

• maintain a lean phenotype on a high fat diet
