enlarged pericardium ( J:99731 )

mortality/aging
embryonic lethality during organogenesis, complete penetrance ( J:50566 )
• homozygous embryos are indistinguishable from wild-type at E8.5, but appear poorly developed and misshaped by E9.5 and undergo resorbtion by E10.5

cardiovascular system
abnormal blood vessel morphology ( J:50566 )
• blood vessels in mutant embryos were enlarged, with defects in the endothelial layer; ectopic vasculature and sporadic discontinuities were also noted, suggesting a failure to develop a functional vasculature system
abnormal angiogenesis ( J:50566 )
• endothelial cells were present throughout mutant embryos; defects occurred in the sprouting, growth, migration and remodeling of endothelial cells
absent vitelline blood vessels ( J:50566 )
• no vascular structures were present in yolk

embryo
absent vitelline blood vessels ( J:50566 )
• no vascular structures were present in yolk
