• Allelic Composition: Taf1d^em1(IMPC)Bay/Taf1d^em1(IMPC)Bay
• Genetic Background: C57BL/6NJ-Taf1d^em1(IMPC)Bay/Mmnc

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

Taf1d^em1(IMPC)Bay/Taf1d^em1(IMPC)Bay mice exhibit embryonic lethality, with embryos recovered at E3.5 as blastocysts but not at E7.5. Blastocysts hatch from the zona pellucida but die after 3 days in culture, never forming outgrowths.

mortality/aging

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

• homozygous embryos are recovered at E3.5 (11% versus expected 25%, n=56) and appear as morulae; no homozygous embryos or excess resorption sites are observed at E7.5

embryo

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

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

reproductive system

failure of embryo implantation ( J:279207 )

• in vitro, embryos fail to hatch and are dead after 3 days in culture, never forming outgrowths
