N normal phenotype
• homozygous mutant embryos at E7.5 and at E8.0 were morphologically abnormal and severely growth retarded
• by E9.5, homozygous mutant embryos were degenerating, and no homozygous mutant progeny were seen in heterozygote intercrosses

• at E7.5, embryonic and extraembryonic ectoderm separated by a groove
• some mesoderm cells found between ectoderm and visceral endoderm
• failure to produce mesendoderm
• anteroposterior axis is not specified
• absence of typical egg cylinder shape at E6.5
• ectoderm did not exhibit its characteristic groove and always showed an abnormally large gap
• numerous dying cells with pyknotic nuclei detected on each side of the gap and within the proamniotic cavity
• failure to produce embryonic mesoderm
• markedly disorganized, does not form a node and fails to produce mesendoderm and embryonic mesoderm
• no primitive node is formed
• no headfolds, allantois and proamniotic cavity remain undivided
• embryos with amniotic folds and with proamniotic cavity divided into 3 compartments but indications of apoptosis also appearing
