N normal phenotype
mortality/aging
• only half of the expected number of mice are born

renal/urinary system
• mice develop severe polycystic renal disease with cysts of varying sizes scattered throughout the cortex
• cysts are bilateral, appear at day 18 at the earliest, are lined with cuboidal epithelium with scanty cytoplasm and are frequently filled with homogeneous eosinopilic fluid or small amounts of floccular material
• cysts and kidney size increase with age
• however, mice do not develop cysts in the salivary glands, pancreas, liver or other glandular organs
• mice develop severe polycystic renal disease
• kidney size increases with age
• mice exhibit dilation of the renal pelvis at a young age

respiratory system
• lung inflammation is observed in some 2- to 4-week old mice
• breakdown of alveolar walls
• mice develop emphysema associated with swollen alveoli and breakdown of alveolar walls

immune system
• intestinal inflammation is observed in some 2- to 4-week old mice
• lung inflammation is observed in some 2- to 4-week old mice

adipose tissue
• adipocytes are smaller in size than in wild-type mice

behavior/neurological

growth/size/body
• mice develop severe polycystic renal disease with cysts of varying sizes scattered throughout the cortex
• cysts are bilateral, appear at day 18 at the earliest, are lined with cuboidal epithelium with scanty cytoplasm and are frequently filled with homogeneous eosinopilic fluid or small amounts of floccular material
• cysts and kidney size increase with age
• however, mice do not develop cysts in the salivary glands, pancreas, liver or other glandular organs
• mice develop severe polycystic renal disease
• kidney size increases with age

digestive/alimentary system
• intestinal inflammation is observed in some 2- to 4-week old mice
