mortality/aging
• embryo absorption is seen between E10 and E12

embryo
• embryos lack vascular morphogenesis at E9.5 in the yolk sac
• mutants exhibit a variable deficit in posterior development
• arrest at the 19 - 23 somite stage
• E9.5 embryos form 19-23 somites compared to 22-16 somites in controls
• 14 of 22 embryos show neural tube kinks anterior to the forelimb
• incomplete somite differentiation: metameric repeated pattern of anterior somites is poorly maintained

growth/size/body
• E9.5 embryos form 19-23 somites compared to 22-16 somites in controls

cardiovascular system
• embryos lack vascular morphogenesis at E9.5 in the yolk sac

nervous system
• 14 of 22 embryos show neural tube kinks anterior to the forelimb
