immune system
increased susceptibility to autoimmune diabetes ( J:98583 )
• 75% of female transgenic mice lacking Ins2 develop diabetes (2 consecutive blood glucose measurements of >250 mg/dl) by 25 weeks of age

homeostasis/metabolism
increased circulating glucose level ( J:98583 )
• >250 mg/dl blood glucose is considered diabetic
