mortality/aging
• no mice survive past P1

cardiovascular system
• vascular integrity defects in internal organs; including the submandibular salivary gland and liver
• telangiectasia at E15.5 in some embryos
• in 50% of embryos at E18.5

homeostasis/metabolism
• in most embryos at E15.5

limbs/digits/tail
• in most mice at E12.5, E15.5, E18.5 and P1 only on the forelimbs
• characterized by the absence of the most posterior digit (5); some mice also lack digit 4
• distal limb morphogenesis is defective in most embryos
• loss of posterior forelimb bud at E12.5

vision/eye
• decrease in the size of the slow cycling band of cells in the mucocutaneous junction region
• at E15.5 the projection of migrating periderm cells is severely diminished and remains incomplete at E16.5
• in about half of the mice at E18.5 and P1

nervous system
• rare, at E15.5 and E18.5

embryo
• loss of posterior forelimb bud at E12.5
