mortality/aging
• only 7% of homozygotes (versus expected 25%) are found at E18.5 but none survive to birth (P0)
• only 8%, 3%, 3%, and 4% of homozygotes (versus expected 25%) are found at E14.5, E15.5, E16.5, and E17.5, respectively
• ~60% of homozygotes die between E9.5 and E11.5 with signs of yolk sac hemorrhage
• the remaining ~40% survive beyond E10.5 with normal development of the heart, vasculature, and hepatic hematopoiesis but die prior to birth with large hemorrhages in the CNS and tail
• only 11% of homozygotes (versus expected 25%) are found at E13.5

embryo
• at E9.5-E11.5, mutant embryos displaying yolk sac hemorrhage (~60%) are growth retarded
• homozygotes that survive beyond E11.5 are strikingly growth retarded
• ~60% of mutant embryos display signs of yolk sac hemorrhage between E9.5 and E11.5
• at E9.5-E11.5, mutant embryos displaying yolk sac hemorrhage (~60%) exhibit a paucity of blood in vitelline vessels

cardiovascular system
• at E9.5-E11.5, mutant embryos with yolk sac hemorrhage occasionally display pericardial effusions

• homozygotes that survive beyond E11.5 exhibit hemorrhages in the central canal of the spinal cord

limbs/digits/tail
• homozygotes that survive beyond E11.5 frequently have short tails
• homozygotes that survive beyond E11.5 may display kinked tails

growth/size/body
• at E9.5-E11.5, mutant embryos displaying yolk sac hemorrhage (~60%) are growth retarded
• homozygotes that survive beyond E11.5 are strikingly growth retarded

homeostasis/metabolism
• at E9.5-E11.5, mutant embryos with yolk sac hemorrhage occasionally display pericardial effusions
• an unregulated tissue factor-FVIIa action and a consequent consumptive coagulopathy appear to underlie the bleeding diathesis in older (>E12.5) mutant embryos
• homozygotes that progress beyond E12.5 display rare intravascular thrombi
• homozygotes that progress beyond E12.5 exhibit deposition of immunoreactive fibrin(ogen) within the hepatic interstitia

craniofacial
• at E18.5, surviving homozygotes may display a sunken cranial fontanelle associated with an intracranial hemorrhage and degeneration of brain tissue

skeleton
• at E18.5, surviving homozygotes may display a sunken cranial fontanelle associated with an intracranial hemorrhage and degeneration of brain tissue

nervous system
• homozygotes that survive beyond E11.5 exhibit intercranial hemorrhages
• homozygotes that survive beyond E11.5 exhibit hemorrhages in the central canal of the spinal cord

immune system
• homozygotes that progress beyond E12.5 exhibit deposition of immunoreactive fibrin(ogen) within the hepatic interstitia

integument
• at E9.5-E11.5, mutant embryos displaying yolk sac hemorrhage (~60%) are visibly pale
• homozygotes that survive beyond E11.5 are strikingly pale
