Phenotype Image Detail
Image
Caption Ventricular and atrial septal defects. A: Transverse sections through the thorax of Hey2tm1Gess/Hey2tm1Gess (-/-) and Hey2+/Hey2tm1Gess (+/-) embryos at stages E12.5, E13.5, E14.5 and E16.5. While all homozygous hearts exhibit a ventricular septal defect (VSD, arrowhead), only E12.5 heterozygotes presented with a VSD that is physiological at this stage. B: An isolated VSD at stage E16.5 in a CD1 background homozygous mutant mouse similar to VSDs seen in C57BL/6 mice. C: Transverse heart sections of a homozygous mutant mouse 5 days after birth showing a VSD combined with a persistent foramen ovale (arrow, right). In control animals the foramen ovale had closed at this time point. The aorta rides over both ventricles (left). LV, RV: left, right ventricle; LA, RA, left, right atrium; IVS: interventricular septum.
