mortality/aging
• ones born alive all died by 3 weeks of age
• homozygous mutant mice were born at a sub-Mendelian ratio

growth/size/body
• widespread cystic dilation of pancreatic ducts and increased cell proliferation
• translucent and minute cystic structures throughout the renal cortex and medulla
• ones born alive are small and sickly
• ones born alive had markedly swollen abdomen
• a pronounced distention of their flanks caused by severe bilateral renomegaly within a few days of birth

renal/urinary system
• translucent and minute cystic structures throughout the renal cortex and medulla
• a pronounced distention of their flanks caused by severe bilateral renomegaly within a few days of birth
• numerous proliferating cells lined the cystic medullary collecting ducts as well as the cortical tubules and cystic glomeruli
• exhibited abnormal development of renal epithelial tubule structures

liver/biliary system
• in the liver the portal tracts were prominent
• ductal plate malformation were present in the biliary tract
• exhibited abnormal development of hepatic epithelial tubule structures
• the majority of epithelial cells lining the gall bladder and some extrahepatic bile ducts are proliferating
• extrahepatic bile ducts were dilated
• severely distended gall bladder, associated with a multifocal acute suppurative cholangitis
