mortality/aging
• homozygotes are viable until the blastocyst stage (E3.5) but die upon implantation and before gastrulation
• mutant embryos are fully resorbed by E6.5

embryo
• at E6.0, presumptive mutant embryos exhibit highly disorganized ectoderm cells
• at E5.5, presumptive mutant embryos have initiated a uterine reaction but resemble implanting blastocysts that are about to collapse
• at E5.5, presumptive mutant embryos are growth retarded
• at E5.5, presumptive mutant embryos are abnormally small and round
• at E5.5, mutant embryos contain parietal endoderm-like cells, suggesting that primitive endoderm primarily fails to differentiate into visceral endoderm
• in vitro, mutant blastocysts are able to form an ICM and trophoblast cell layer outgrowths; however, further differentiation of ICM is curtailed and visceral endoderm differentiation fails
• at E6.0, presumptive mutant embryos lack an identifiable extraembryonic tissue
• at E6.0, presumptive mutant embryos lack ectoplacental cavities
• at E6.0, presumptive mutant embryos lack a visible parietal endoderm cell layer
• at E6.0, presumptive mutant embryos lack proamniotic cavities
• at E6.0, presumptive mutant embryos lack a visible visceral endoderm cell layer

growth/size/body
• at E5.5, presumptive mutant embryos are growth retarded
• at E5.5, presumptive mutant embryos are abnormally small and round

mortality/aging
• die within the first 2 days after birth

renal/urinary system
• higher density of mature glomeruli in the medulla region compared to the periphery unlike in controls
• 12-16% of glomeruli become cystic
• expression analysis indicates a defect in proximal and intermediate regions of the S-shaped bodies development during tubule development
• S-shaped bodies appear less convoluted
• decrease in proliferation in comma-shaped bodies and a stronger decrease in the future proximal tubule of S-shaped bodies at E16.5
• increase in apoptosis in kidney epithelium but not stroma at E16.5
• strong increase in apoptosis in late mutant nephron tubules and a more moderate increase in S-shaped bodies
• occasional
• decrease in tubular structures
• reduction of 43.5% in mature glomeruli mutant kidneys
• higher density of mature glomeruli in the medulla region compared to the periphery unlike in controls
• medullar elongated loop of Henle tubules are not visible at P0
