Casc3tm1.1(KOMP)Vlcg/Casc3tm1.1(KOMP)Vlcg mice exhibit embryonic lethality, with embryos recovered at E7.5 but not at E9.5. Embryos are smaller and although a primitive streak has formed, no other hallmarks typical of gastrulation are seen.

mortality/aging
embryonic lethality between implantation and placentation, complete penetrance ( J:279207 )
• homozygous embryos are present at E7.5 (11% versus expected 25%, n=44); no homozygous embryos are recovered at E9.5

embryo
failure to gastrulate ( J:279207 )
• although the primitive streak has formed, no other hallmarks typical of gastrulating embryos are observed at E7.5
decreased embryo size ( J:279207 )
• embryos appear smaller than controls at E7.5
absent head fold ( J:279207 )
• no head folds are present at E7.5
absent primitive node ( J:279207 )
• no morphological embryonic node is present at E7.5

growth/size/body
decreased embryo size ( J:279207 )
• embryos appear smaller than controls at E7.5
