cardiovascular system phenotype ( J:161948 )
N
• unlike in mice homozygous for other alleles of this gene, heart chamber formation is normal
abnormal atrioventricular valve morphology ( J:161948 )
• atrioventricular valve thickness is increased due to an increase in mesenchyme compared to in wild-type mice
abnormal heart ventricle outflow tract morphology ( J:161948 )
• outflow tract valve thickness is increased due to an increase in mesenchyme compared to in wild-type mice
abnormal cardiovascular system physiology ( J:161948 )
• in vivo proliferation of outflow tract (OFT) and atrioventricular (AV) valve mesenchyme and endocardial cells is increased compared to in wild-type mice
• proliferation of mesenchyme and endocardial cells from cushion explants in culture is increased compared to wild-type explants
• however, apoptosis of mesenchyme cells from outflow tract valves is normal

respiratory system
respiratory system phenotype ( J:161948 )
N
• unlike in mice homozygous for other alleles of this gene, lung development is normal
