N | normal phenotype |
• embryos typically arrest and die between E9.5 and E11.5
|
• embryos are retarded in growth by E7.5
|
• in most cases, do not undergo axial rotation
|
• exhibit a truncated posterior at E9.5
|
• embryos typically arrest between E9.5 and E11.5
|
• embryos are retarded in growth by E7.5
|
• neural folds are not fused at E9.5
|
• by E8.5, exhibit disproportionate growth of the extraembryonic structures compared with embryonic ectoderm, resulting in a large yolk sac and allantois compared to embryo size
|
• overgrowth of the yolk sac is seen at E8.5
|
• exhibit an increased prevalence of apical electron dense structures in the yolk sac visceral endoderm
|
• variability in chorioallantoic fusion
|
• neural folds are not fused at E9.5

N | normal phenotype |
• about 40% do not survive development
|
• embryos are smaller and growth retarded by E11.5
|
• embryos are smaller by E11.5
|
• those that survive development are born runted (about 20% smaller) due to developmental growth retardation, with small size continuing into adulthood
|
• embryos are smaller and growth retarded by E11.5
|
• embryos are smaller by E11.5
