mortality/aging

embryonic lethality during organogenesis, incomplete penetrance ( J:49154 )

• a number of homozygous mutant embryos are found dead or resorbed at E9.5

embryo

abnormal gastrulation ( J:49154 )

• at E9.5, the amount of Mox-1-positive paraxial mesoderm is reduced

abnormal somite development ( J:49154 )

• at E9.5, paraxial mesoderm is not organized into somites

absent somites ( J:49154 )

• at E9.5, homozygotes show absence of somite formation
