• N: normal phenotype

Gtpbp4^em1(IMPC)Tcp/Gtpbp4^em1(IMPC)Tcp mice exhibit embryonic lethality, with embryos recovered at E3.5 as early blastocysts but not at E7.5. Blastocysts fail to hatch from the zona pellucida and die after 3 days in culture.

embryo

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

• in vitro outgrowth assays show that blastocysts fail to hatch from the zona pellucida and are dead after 3 days in culture

mortality/aging

embryonic lethality prior to organogenesis ( J:211773 )

IMPC - TCP

preweaning lethality, complete penetrance ( J:211773 )

IMPC - TCP

embryonic lethality prior to organogenesis, complete penetrance ( J:279207 )

• although early blastocysts are recovered at E3.5, no homozygous embryos are found at E7.5

• however, excess resorption sites suggest that embryos elicit a decidual response in vivo
