mortality/aging
• fewer than expected mice are present at weaning
• fewer than expected mice are present between E12.5 and E18.5

cardiovascular system
• mice with bleeding exhibit dilated ventral skin blood vessels with poor mural cell coverage compared with wild-type mice
• mice with bleeding exhibit dilated ventral skin blood vessels with poor mural cell coverage compared with wild-type mice
• mice with bleeding exhibit dilated ventral skin blood vessels with poor mural cell coverage compared with wild-type mice
• in some mice
• at E14.5, some mice exhibit subcutaneous hemorrhage unlike wild-type mice
• at E18.5, some mice exhibit hemorrhage in the neck, head, limbs, and other areas of the body unlike wild-type mice
• at E18.5, some mice exhibit hemorrhagic lesions in pericardial cavities, periocular tissues, salivary glands, and subcutaneous tissues unlike wild-type mice
• however, blood coagulation is normal
