mortality/aging

postnatal lethality, complete penetrance ( J:92799 )

• only the double homozygous mutants display postnatal lethality

muscle

abnormal myogenesis ( J:92799 )

• skeletal muscle differentiation is seen at E12.5 however myogenesis is still severely impaired such that mutants essentially lack skeletal muscle at birth

absent skeletal muscle ( J:92799 )

• mutants essentially lack skeletal muscle throughout the body including the head
