mortality/aging
• Background Sensitivity: lethality occurs earlier (14 - 21 days of age) on a mixed BALB/c and CAST/EiJ background
• die around 4 weeks of age from kidney failure

renal/urinary system
• occasional cystic dilation of Bowman's space involving about 6% of glomeruli is seen
• progressive kidney enlargement is detectable by 2 weeks of age (J:13276)
• cells lining the cysts become increasingly flattened with age and the number of mitoses in cyst-lining epithelial cells is increased (J:13276)
• at birth tubular dilation and early cyst formation is in the inner cortical zone and tubules undergo progressive cystic enlargement resulting in nephron destruction and the location of the cysts gradually shifts from the proximal tubules to the collecting ducts (J:13276)
• at birth cysts are seen in subcortical areas and at later stages cystic lesions are found predominantly in collecting tubular segments (J:21554)
• cysts are radially arrayed, a pattern typical of cysts in the collecting ducts and occasional cystic dilation of Bowman's space involving about 6% of glomeruli is seen (J:36348)
• Background Sensitivity: kidney cysts develop earlier on a mixed BALB/c and CAST/EiJ background (J:36348)

growth/size
• from massive enlargement of kidneys (J:21554)
• Background Sensitivity: distension is seen earlier (9 - 15 days of age) on a mixed BALB/c and CAST/EiJ background (J:36348)

behavior/neurological
• become increasingly lethargic after birth

homeostasis/metabolism
• progressive elevation in plasma urea levels with age 31+/-9 and 88+/-14 vs 18+/-1 and 24+/-4 in controls at day 15 and 25, respectively; however plasma bilirubin is similar to controls

liver/biliary system
• epithelial hyperplasia with a 50% increase in biliary epithelial cells by day 5, a 60% increase by day 15, and a 100% increase by day 25 on a per square mm basis
• the number of bile ducts per square mm is increased
• dilation of the cystic, hepatic, and common bile ducts is seen, always linked to the presence of kidney cysts; however, the gallbladdr was not dilated and had normal histology
• increase in the frequency of portal areas in which the portal vein is surrounded by irregularly shaped bile ducts and increased epithelial cell proliferation

endocrine/exocrine glands
• epithelial hyperplasia with a 50% increase in biliary epithelial cells by day 5, a 60% increase by day 15, and a 100% increase by day 25 on a per square mm basis
• the number of bile ducts per square mm is increased
• dilation of the cystic, hepatic, and common bile ducts is seen, always linked to the presence of kidney cysts; however, the gallbladdr was not dilated and had normal histology
