N normal phenotype
liver/biliary system
increased hepatocellular carcinoma incidence ( J:132670 )
• incidence is decreased compared to Iqgap1tm1Vs single homozygotes but is increased compared to controls

mortality/aging
mortality/aging ( J:132670 )
N
• unlike Iqgap1tm1Vs single homozygotes, survival durations are not significantly different from controls

neoplasm
increased hepatocellular carcinoma incidence ( J:132670 )
• incidence is decreased compared to Iqgap1tm1Vs single homozygotes but is increased compared to controls
decreased tumor growth/size ( J:132670 )
• when present hepatocellular carcinomas are smaller than those in Iqgap1tm1Vs single homozygotes

homeostasis/metabolism
homeostasis/metabolism phenotype ( J:132670 )
N
• unlike Iqgap2tm1Vs single homozygotes, levels of aspartate transaminase are similar to controls in mice at 4 and 8 months of age
