phenotype observed in females
phenotype observed in males
N normal phenotype
adipose tissue
• female mice have a 2-fold gain in mg of BAT compared to littermate controls
• female mice have almost a 2-fold increase in fat pad weight compared to wild-type controls
• female mice have about a 2-fold increase in fat pad weight compared to wild-type controls
• female mice have about a 2-fold increase in fat pad weight compared to wild-type controls
• female and male mice have a 1.6-fold gain in percentage of body fat compared to littermate controls

behavior/neurological
N
• food consumption and circulating levels of leptin are close to wild-type levels, which is significantly less compared to mice with only the Ay mutant allele
• locomotor activity is about 1.5-fold higher compared to wild-type control mice

growth/size/body
N
• mean body weight and length of 20-23 week old mice is similar to wild-type littermate controls and is less than is observed in mice with only the Ay mutant allele
• weight and percentage of body fat in female mice is higher than in wild-type mice but is significantly lower than is observed in mice with only the Ay mutant allele
• male but not female mice gain weight at a greater rate than littermate controls starting at six weeks of age
• rate of weight gain in male mice is significantly less than in Ay heterozygotes

pigmentation
• mice have a yellow coat color

integument
• mice have a yellow coat color
