Ltv1em1(IMPC)J/Ltv1em1(IMPC)J mice exhibit embryonic lethality, with embryos recovered at E3.5, that appear as morula, but no embryos at E7.5. Mutants grown in vitro fail to hatch from the zona pellucida, never forming blastocysts.

embryo
• in vitro, embryos fail to form blastocysts and are dead after 3 days in culture
• in vitro, embryos fail to hatch from the zona pellucida after 3 days in culture

mortality/aging
• morula-like embryos are present at E3.5 (15% versus expected 25%, n=27); no homozygous embryos or excess resorption sites are observed at E7.5
