Ddx18em1(IMPC)Bay/Ddx18em1(IMPC)Bay mice exhibit embryonic lethality, with embryos recovered at E3.5 as uncompacted morulae but not at E7.5. Mutants fail to hatch from the zona pellucida and are dead after 3 days in culture.

mortality/aging
• homozygous embryos can be recovered at E3.5 (12% versus expected 25%, n=34) and appear as uncompacted morulae; no homozygous embryos or excess resorption sites are observed at E7.5

embryo
• in vitro, embryos fail to hatch from the zona pellucida and are dead after 3 days in culture
• embryos recovered at E3.5 appear as uncompacted morulae
