♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:228222 )

• although present at normal Mendelian ratios up to E9.5, homozygous mutant embryos are resorbed at E10.5, with no viable embryos detected at P0

embryo

embryonic growth arrest ( J:228222 )

• developmental arrest before E10.5

embryonic growth retardation ( J:228222 )

• embryos are developmentally delayed at E9.5

abnormal extraembryonic tissue physiology ( J:228222 )

• accumulation of Cdkn2a (an inhibitor of cell cycle progression, also known as p19^ARF) mRNA in the yolk sac at E9.5

growth/size/body

embryonic growth retardation ( J:228222 )

• embryos are developmentally delayed at E9.5

cellular

decreased fibroblast proliferation ( J:228222 )

• after Cre retrovirus infection (to delete the floxed allele), primary mouse embryonic fibroblasts (MEFs) derived from E13.5 embryos show significantly decreased cell proliferation relative to wild-type MEFs

• no differences in oncogene-induced cellular replicative senescence or apoptosis are observed

• defect in MEF proliferation can be rescued by beta-TrCP2 overexpression, but not by beta-TrCP1 overexpression

• arrest in MEF proliferation is induced by stabilization and abnormal accumulation of Cdkn2a (also known as p19^ARF)

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:228222 )

• phenotype is stated to be identical to that of Fbxw11^tm1Nakay homozygotes, indicating that concomitant inactivation of Cdkn2a does not rescue the lethal phenotype
