N normal phenotype
mortality/aging
• homozygotes die around E10.5; no homozygous newborns are ever found

embryo
• at E7.5 and 8.5 there is minimal apoptosis compared to wild-type embryos
• at E9.5. truncations in the anterior regions of homozygous embryos are seen
• at E7.5 homozygotes are smaller than littermates
• the anterior definitive endoderm is absent in mutants at E7.5
• at E8.5 headfolds are reduced in size
• at early somite stages truncations in the anterior neural folds are observed
• induction of anterior neuroectoderm fails to occur and is missing in mutant embryos
• mutants have less cell proliferation in the region of the anterior neuroectoderm
• at E7.5 and 8.0, mutants lack prechordal plate
• the anterior visceral endoderm is mislocalized distally compared to wild-type embryos
• there is little proliferation observed at E6.0 in the anterior visceral endoderm of mutants

growth/size/body
• at E7.5 homozygotes are smaller than littermates

cellular
• at E7.5 and 8.5 there is minimal apoptosis compared to wild-type embryos

nervous system
• induction of anterior neuroectoderm fails to occur and is missing in mutant embryos
• mutants have less cell proliferation in the region of the anterior neuroectoderm
• at E10.5, homozygotes display a severe forebrain truncation
• the diencephalon is entirely absent at E8.0
• at E8.5 and E9.5, markers for telencephalon forebrain are absent in homozygotes
• mutants have less cell proliferation in the region of the anterior neuroectoderm
