N normal phenotype
mortality/aging
embryonic lethality between implantation and somite formation, complete penetrance ( J:73507 )
• embryos die around day 7.5 of gestation due to abnormal embryonic ectoderm development

embryo
abnormal embryonic tissue morphology ( J:73507 )
• analysis of day 8.5 conceptuses shows absence of embryonic ectoderm derivatives, but apparently normal yolk-sac membrane and tissues of mesoderm origin
• well-organized columnar embryonic ectoderm epithelium is indistinguishable in day 7.0 embryos
