embryo
open neural tube ( J:225273 )
• a high percentage of E12.5 embryos exhibit neural tube defects
spina bifida ( J:225273 )
• several E11.5 and E12.5 embryos exhibit spina bifida

mortality/aging
lethality throughout fetal growth and development, incomplete penetrance ( J:225273 )
• fewer double heterozygous animals (4.6%) are produced than expected (25%) from a heterozygote x heterozygote mating
• a significant drop in viability occurs between E15.5 and birth
postnatal lethality, complete penetrance ( J:225273 )
• no pups survive beyond P14

nervous system
open neural tube ( J:225273 )
• a high percentage of E12.5 embryos exhibit neural tube defects
spina bifida ( J:225273 )
• several E11.5 and E12.5 embryos exhibit spina bifida
holoprosencephaly ( J:225273 )
• several E11.5 and E12.5 embryos exhibit holoprosencephaly
