mortality/aging
• embryos are viable and indistinguishable from controls at least until E14.5; however, no mice are recovered postnatally

cardiovascular system
• misshapen heart at E14.5
• however, no ventricular septal defects are detected at E14.5
• right ventricular wall thickness is significantly reduced at E14.5
• however, left ventricular wall thickness is normal
• right ventricular hypoplasia at E14.5

cellular
• at E12.5, cardiomyocyte mitotic index is significantly reduced in the right ventricles (but not in the left ventricles), as shown by phospho-histone H3 staining
