renal/urinary system
• mice develop kidney cysts at the same frequency as in Cys1cpk homozygotes but cysts are larger in size
• mice exhibit an increase in the number of advanced stage cysts compared to in Cys1cpk homozygotes
• cysts are primarily restricted to the collecting ducts with few proximal tubule cysts
• proliferation and apoptosis of cystic kidneys is increased compared to in Cys1cpk homozygotes
• P10, kidneys are larger than in Cys1cpk homozygotes
• at P3 and P10, kidney weight to body weight ratio is larger than in Cys1cpk homozygotes

homeostasis/metabolism
• compared to in Cys1cpk homozygotes at P10
