N normal phenotype
mortality/aging
• mutants die at 9-12 weeks of age; almost complete penetrance
• mutants placed on a high sugar diet to counteract hypoglycemia liver longer

endocrine/exocrine glands
• organization of alpha and delta cells is disrupted in islets
• hyperplasia of the islets of Langerhans
• reduced numbers of alpha cells in islets
• islets are densely packed with beta-cells
• reduced numbers of delta cells in islets
• mutants placed on a high sugar diet to counteract hypoglycemia develop solid pancreatic tumors between 10 and 20 weeks of age; tumors are pure beta-cell tumors
• no evidence that tumors metastasize other organs

neoplasm
• mutants placed on a high sugar diet to counteract hypoglycemia develop solid pancreatic tumors between 10 and 20 weeks of age; tumors are pure beta-cell tumors
• no evidence that tumors metastasize other organs
