• at 6 months of age, both males and females carrying the paternally-inherited deletion allele show increases in daily food intake normalized to body weight (22% or 32%, respectively; at 3 months, males show significant hyperphagia relative to wild-type males, but to a lesser degree than at 6 months, while in females carrying the paternally-inherited deletion allele, daily food intake increases do not reach significance

• morphology of pituitary gland in mutants is normal (J:131427)

homeostasis/metabolism
• when mice are restricted to 80% of their normal food intake levels, wild-type mice gradually lose weight but animals carrying the paternally-inherited deletion allele are better at maintaining their weight (females are significantly better, but males also show improved weight stability compared to wild-type)
• when fed a high-fat diet for 4 months from 8 weeks of age, mutants carrying the paternally-inherited deletion gain less weight than wild-type littermates, with the differences more pronounced in males
• on a high-fat diet, males carrying the paternally-inherited deletion allele have lower resting blood glucose levels and display a smaller peak level after glucose injecion compared to wild-type males

adipose tissue
• when fed a high-fat diet for 4 months, mutants carrying the paternally-inherited deletion allele have significantly lower body fat than wild-type animals (mutant males -6.9%, mutant females -7.2% lower than wild-type)
• 5 month-old mutant males on regular chow diet show an insignificant trend (-3.6%) toward decreased body fat content while females show a significant decrease of 4.2% relative to wild-type; 9-month old animals on a regular chow diet significantly lower body fat content (-9% in mutant males, -5% in females)
• on high-fat and normal chow diets, animals carrying the paternally-inherited deletion allele display decreased fat storage compared to wild-type animals

digestive/alimentary system
• stomachs in animals receiving paternally-inherited mutant allele are significantly smaller than in wild-type littermates; at P5 and 13, stomachs are 67 and 68% the size of wild-type

liver/biliary system
• size is strikingly reduced in size upon examination at P5 and 13
• at P5, liver weight is 72% of wild-type animals, and at p13, liver weight is only 56% of wild-type

cellular
• the Snord116 cluster is imprinted and the maternal copy is silenced during oogenesis; only inheritance of the paternal allele with the Snord116 cluster deletion produces the growth deficiency and polyphagia phenotypes in mice
• when offspring have maternal inheritance of the deleted allele, they are normal in size and show normal lifespans
