mortality/aging
• most homozygotes survive to 20 weeks but not longer than 25 weeks

renal/urinary system
• E13.5 kidneys grown in vitro for 5 days with 8-Br-cAMP in the culture media display cyst formation, with higher cystic percentage than heterozygous or wild-type kidneys
• isolated cysts lined with cuboidal epithelial cells are seen by P3 (J:11885)
• by P15, cysts lined with flattened epithelial cells cover about 15% of the cortex region (J:11885)
• cysts are mostly cortical with some outer medullary involvement; however no cysts are seen in the liver spleen, or pancreas (J:11885)
• by 7 weeks of age, extensive renal cysts lined by flattened epithelium are found in the kidney cortex (J:79600)
• by 7 weeks of age, extensive renal cysts lined by flattened epithelium are found in the kidney medulla
• cultured kidneys in the presence of 8-bromo-cAMP show 3-fold higher cystogenic potentials than controls and treatment of these cultures with Gant61, a small molecule GLI antagonist, or Sant2, a small molecule SMO antagonist, inhibitors reduces cystogenic potential (J:213263)
• by 7 weeks of age, extensive cystic lesions replace normal renal parenchyma (J:79600)
• palpable by 7 weeks of age (J:11885)
• at 7 weeks of age, a 4-fold increase in kidney volume is observed, as assessed by MRI imaging (J:79600)
• elevation in ratio of percent kidney weight to body weight at 7 weeks of age
• at 7 weeks of age, as shown by MRI imaging

homeostasis/metabolism
• linear increase in serum creatinine with age from 0.3 mg/dl at 40 days to 1.0 mg/dl at 120 day compared to less than 0.12 mg/dl in controls

behavior/neurological
• females do not consistently care for their pups; however both homozygous males and females are fertile

growth/size/body
• E13.5 kidneys grown in vitro for 5 days with 8-Br-cAMP in the culture media display cyst formation, with higher cystic percentage than heterozygous or wild-type kidneys
