Snapc2^em1(IMPC)J/Snapc2^em1(IMPC)J mice exhibit embryonic lethality, with embryos recovered at E3.5 but not at E7.5. Embryos at E3.5 appear as dying morulae. Mutants fail to hatch from the zona pellucida and never reach blastocyst stage in culture.

embryo

failure of blastocyst formation ( J:279207 )

• in vitro, embryos fail to hatch and never reach a morphological blastocyst stage after 3 days in culture

failure of blastocyst to hatch from the zona pellucida ( J:279207 )

• in vitro, embryos fail to hatch from the zona pellucida with apparent cell death after 3 days in culture

embryonic growth arrest ( J:279207 )

• embryos recovered at E3.5 appear as dying morulae

• morulae show no further development after 3 days in culture

abnormal morula morphology ( J:279207 )

• morulas recovered at E3.5 appear to be dying

mortality/aging

embryonic lethality prior to organogenesis ( J:211773 )

IMPC - JAX

preweaning lethality, complete penetrance ( J:211773 )

IMPC - JAX

embryonic lethality before implantation, complete penetrance ( J:279207 )

• homozygous embryos are recovered at E3.5 (8% versus expected 25%, n=36) and appear to arrest/die prior to blastocyst formation; no embryos or excess resorption sites are observed at E7.5
