cardiovascular system
• endocardial cushions within the outflow tract appear grossly reduced in size
• in the atrioventricular canal, there is malalignment of the atrial septum, although the septum does meet the endocardial cushions in more distal areas
• endocardial cushions are hypoplastic and fail to elongate and form atrioventricular valve primordia at E13.5
• at E12.5, cell proliferation within the endocardial cushion is reduced by 75%
• defects in valve maturation
• atrioventricular valve primordia do not form at E13.5
• incomplete formation of the atrial septum
• mutants exhibit increased blood pooling
