mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:75950 )

• embryos survive until E10.5, but are being resorbed by E11.5

cardiovascular system

abnormal heart development ( J:75950 )

• abnormal heart chamber morphogenesis

failure of heart looping ( J:75950 )

• failure of heart looping

embryo

absent second pharyngeal arch ( J:75950 )

• lack of branchial arches 2 and 3
