mortality/aging
• most pups die at birth without inflating their lungs
• about 10% of homozygotes survive to maturity

cardiovascular system
• at E14.5 embryos have a congested venous system
• at E14.5 and E18.5 both atria are dilated
• surviving homozygous male mutants have significantly increased heart weights
• at E14.5 and E18.5 the ventricles are smaller
• at E14.5 and E18.5 reduced trabecular structure is seen
• at E14.5 ventricular septal abnormalities are seen
• at E14.5 and E18.5 the ventricles have thinner walls compared to wild-type mice
• in some cases an increased pericardial space is seen
• 12 and 16 month old surviving homozygous male mutants display cardiac fibrosis
