mortality/aging

embryonic lethality, complete penetrance ( J:62882 )

• embryo absorption is seen between E10 and E12

embryo

absent vitelline blood vessels ( J:62882 )

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

abnormal rostral-caudal axis patterning ( J:62882 )

• mutants exhibit a variable deficit in posterior development

embryonic growth arrest ( J:62882 )

• arrest at the 19 - 23 somite stage

embryonic growth retardation ( J:62882 )

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