mortality/aging
embryonic lethality at implantation, complete penetrance ( J:70591 )
• homozygous mutant embryos die between 3.5 and 4.5 dpc

reproductive system
failure of embryo implantation ( J:70591 )
• at 3.5 dpc, homozygous null blastocysts appear normal, with an identifiable inner cell mass and an inner cavity; however, mutant blastocysts do not appear to implant
