mortality/aging
lethality throughout fetal growth and development, complete penetrance ( J:105920 )
• no homozygous animals are recovered postnatally; embryos survive to E15.5 then display a drop in viability

embryo
embryonic growth retardation ( J:105920 )
• embryos are delayed by about 1 day
abnormal neural tube closure ( J:105920 )
• 30-50% of embryos isolated at E10.5-11.5 have a defect in spinal neural tube closure; in some, the neural tube remained completely open, while in others it is closed at discrete points with the intervening regions remaining open
spina bifida ( J:105920 )
• later in development, some embryos display spina bifida

nervous system
abnormal neural tube closure ( J:105920 )
• 30-50% of embryos isolated at E10.5-11.5 have a defect in spinal neural tube closure; in some, the neural tube remained completely open, while in others it is closed at discrete points with the intervening regions remaining open
spina bifida ( J:105920 )
• later in development, some embryos display spina bifida

growth/size/body
embryonic growth retardation ( J:105920 )
