N normal phenotype
mortality/aging
• mice die by 6 to 7 days after birth

digestive/alimentary system
• at E14.5, no acinar cells are detected unlike in wild-type mice
• by E18.5, few acinar cells appear in late embryonic development
• mice exhibit impaired milk digestion

growth/size/body
• moderate at birth

endocrine/exocrine glands
• at birth the pancreas is small and altered compared to in wild-type mice
• unlike in wild-type mice, the duodenal part of the pancreas exhibits weak branching and the splenic part exhibits no branching
• at E14.5, no acinar cells are detected unlike in wild-type mice
• by E18.5, few acinar cells appear in late embryonic development
• at E11.5, mice exhibit an increase in glucagon producing cells
• the number of islets is decreased compared to wild-type mice
• the endocrine epithelium is disrupted with alpha cells not surrounded by beta cells and long rather than circular islet-like structures
• at E13.5, the pancreatic epithelial mass is reduced and pancreatic bud branching is weaker than in wild-type mice
• mice exhibit a 40% decrease in the number of proliferating cells compared to in wild-type mice
• at E11.5, mice exhibit premature differentiation into endocrine cells

cellular
• at E11.5, mice exhibit premature differentiation into endocrine cells
