mortality/aging
mortality/aging ( J:157446 )
N
• presence of the transgene recues the lethality observed in double null animals; number of embryos observed at 12.5-14.5 days post coitus is equal to number of wild-type embryos collected

nervous system
exencephaly ( J:157446 )
• transgene expression does not prevent exencephaly with about 20% embryos at 12.5-14.5 dpc

cardiovascular system
cardiovascular system phenotype ( J:157446 )
N
• lethality associated with midgestational cardiovascular failure is rescued
