immune system
• in female mice
• in female, but not male, mice
• in female, but not male, mice
• female mice exhibit a decrease in CD8alpha,beta T cells compared with wild-type mice
• male mice exhibit an increase in CD8alpha,beta T cells compared with wild-type mice
• in female mice
• in female mice
• in female mice
• in female mice

homeostasis/metabolism
• mice exhibit reduced metabolized energy compared with wild-type mice
• Background Sensitivity: when normalized to individual body weight, male mice congenic on a C3 background exhibit increased metabolized energy while male mice exhibit only a tendency compared with wild-type mice whereas on a 129 background only female mice exhibit increased metabolized energy compared with wild-type mice
• alpha-amylase activity is decreased compared to in wild-type mice

skeleton
• whole body bone mineral content is reduced in female mice and tends to be reduced in male mice compared with wild-type mice
• however, bone content related to body weight is normal
• whole body bone mineral density is reduced compared to in wild-type mice
• specific bone mineral density is increased compared to in wild-type mice
• however, bone content related to body weight is normal

growth/size/body
• average body lean body mass and the average fat to lean mass ratio are reduced compared to in wild-type mice
• at 6 weeks, average body weight is decreased compared with wild-type mice
• average fat-free dry mass is reduced compared to in wild-type mice
• however, body weight normalized to energy uptake is normal
• mice are shorter than wild-type mice
• mice fasted for 2 days exhibit a greater loss of body weight compared with similarly treated wild-type mice

cardiovascular system
• pulse and heart rate in female mice are decreased compared to in wild-type mice
• the Q amplitude is increased compared to in wild-type mice

adipose tissue
• average body fat content and the average fat to lean mass ratio are reduced compared to in wild-type mice

behavior/neurological
• mice consume less food and have a reduced energy uptake compared with wild-type mice
• mice exhibit a tendency towards reduced locomotor activity compared with wild-type mice

digestive/alimentary system
• mice produce less feces than wild-type mice

hematopoietic system
• in female mice
• in female, but not male, mice
• in female, but not male, mice
• female mice exhibit a decrease in CD8alpha,beta T cells compared with wild-type mice
• male mice exhibit an increase in CD8alpha,beta T cells compared with wild-type mice
• in female mice
• in female mice
• in female mice
• in female mice
