mortality/aging

lethality throughout fetal growth and development, complete penetrance ( J:141749 )

• homozygotes are embryonic lethal with development stopping at E15

cardiovascular system

internal hemorrhage ( J:141749 )

• E15 embryos are pale and have internal hemorrhages

hematopoietic system

abnormal erythropoiesis ( J:141749 )

• only a small fraction of the cells fully differentiate into erythrocytes in the fetal liver of E15 embryos with an accumulation occurring of Ter119^int/CD71^int immature cells
