N
• females with a paternally inherited mutant allele are viable
• at E16.5-E18.5 the proportion of female embryos with a maternally inherited mutant allele was dramatically reduced to 5/64
• females were readily detected at E13.5 and E14.5
• by weaning no females with a maternally inherited mutant allele were detected

embryo
• at E9.5 fetal blood vessels remain restricted to the chorioallantoic plate regions in females with a maternally inherited mutant allele unlike in wild-type littermate controls
• vascular network and trophoblast cells in the labyrinth layer are more loosely organized in females with a maternally inherited mutant allele
• slightly slower growth in females with a maternally inherited mutant allele at E12.5
• decreased in size at E9.5 in females with a maternally inherited mutant allele
• at E9.5 in females with a maternally inherited mutant allele
• decrease in the number of spongiotrophoblast-specific protein alpha-positive cells in the spongiotrophoblast cell layer in females with a maternally inherited mutant allele at E12.5, E14.5 and E16.5
• in females with a maternally inherited mutant allele at E9.5, E12.5 and E14.5
• smaller in females with a maternally inherited mutant allele at E12.5

cardiovascular system
• at E9.5 fetal blood vessels remain restricted to the chorioallantoic plate regions in females with a maternally inherited mutant allele unlike in wild-type littermate controls
• vascular network and trophoblast cells in the labyrinth layer are more loosely organized in females with a maternally inherited mutant allele
• seen at E14.5 and E16.5 in all females with a maternally inherited mutant allele
• peripheral hemorrhage in embryos with small placentas at E14.5 and E16.5

homeostasis/metabolism
• in embryos with small placentas at E14.5 and E16.5

growth/size/body
• slightly slower growth in females with a maternally inherited mutant allele at E12.5
