mortality/aging
• most homozygotes die between E9.5 and E10.5
• no homozygotes are recovered at or after E11.5

embryo
• at E9.5, most homozygous mutant embryos remain unturned
• at E9.5, homozygotes exhibit a small and underdeveloped caudal portion
• at E9.5, most homozygous mutant embryos are ~25% to ~50% the size of wild-type embryos
• abnormal folding of the neuroectoderm is noted at the level of the cephalic folds and of the neural tube
• at E9.5, homozygotes fail to close their cephalic neural folds
• at E9.5, the mutant neural tube is closed at the level of the otic vesicle but remains open beyond the midbrain-forebrain boundary
• abnormal folding of the neuroectoderm is noted at the level of the cephalic folds and of the neural tube
• at E9.5, homozygotes exhibit a wavy and disorganized neural tube
• in addition, the neural tube is often curved and infiltrated with pyknotic cells
• at E8.5, the mutant notochord is consistently smaller or even absent
• at E9.5, the allantois is often abnormal and either resorbing or tuberous
• allantois is often overgrown with a "bleb" at its extremity

nervous system
• at E9.5, homozygotes fail to close their cephalic neural folds
• at E9.5, the mutant neural tube is closed at the level of the otic vesicle but remains open beyond the midbrain-forebrain boundary
• abnormal folding of the neuroectoderm is noted at the level of the cephalic folds and of the neural tube
• at E9.5, homozygotes exhibit a wavy and disorganized neural tube
• in addition, the neural tube is often curved and infiltrated with pyknotic cells

growth/size/body
• at E9.5, most homozygous mutant embryos are ~25% to ~50% the size of wild-type embryos
• at E9.5, homozygotes display a disproportionately bulky and dilated head

cardiovascular system
• at E9.5, blood circulation is essentially absent in the visceral yolk sac and in mutant embryos
• however, all homozygotes at this stage show normal decidual sizes and normal beating of the heart

behavior/neurological
• no increased investigation of displaced familiar objects, similar to 129P2 control but unlike C57BL/6 control
• given a chose of two novel food sources they choose a food they have already seen another mouse eat
• increased time spent exploring open arms of an elevated + maze
• increased social approach of a strange mouse as opposed to investigating an empty cage or examining a pre-exposed familiar mouse
• less time is spent re-investigating a strange mouse during second exposure to that mouse
• given a chose of two novel food sources they choose a food they have already seen another mouse eat
