phenotype observed in females
phenotype observed in males
N normal phenotype
growth/size/body
• at 3 months of age, mice display a mild decrease in body weight compared to wild-type mice

nervous system
• agouti-related protein expressing neurons are slightly more hyperpolarized than in wild-type mice and do not respond electrophysically to glucose as do wild-type cells

behavior/neurological
• following treatment with melanotan II, mice exhibit less food intake than similarly treated wild-type

homeostasis/metabolism
N
• despite reduction in weight, mice exhibit normal food intake, resting metabolic rate, daily energy expenditure, response to a high fat diet, leptin, glucose and adiponectin levels, and glucose and insulin tolerance
