N normal phenotype
mortality/aging
• though alive 1 day before birth, fewer than expect mice survive the 2 to 3 hours after birth before nursing

endocrine/exocrine glands
• at E16, mice have fewer glucagon producing cells than in wild-type mice
• however, the number of glucagon producing cells at E12 is normal
• mice lack a pancreas
• however, all endocrine islet cell types are detected after birth in the mesentery that normally harbors the pancreas until E16

homeostasis/metabolism
• at birth
• at birth

hematopoietic system
• unlike in wild-type mice, glucagon producing cells and pancreatic endocrine cells are located in the spleen at birth

growth/size/body

immune system
• unlike in wild-type mice, glucagon producing cells and pancreatic endocrine cells are located in the spleen at birth
