cardiovascular system
• in the ventricles
• does not display organized clusters of smooth muscle cells or vascular structures unlike wild-type myocardium
• completely penetrant at E16.5
• distended, abnormally positioned relative to the ventricle
• rounded without apex
• reduced trabeculation, thinner compact myocardium and disorganized ventricular myocardium
• reduced myocardial cytokinesis
• with tearing of the membranous region at E14.5
• thin with tearing of the membranous region at E14.5
• however, initial development is normal unlike in null mice
• on the surface of the heart at E11.5 and persisting until death at E16.5
• at E11.5

homeostasis/metabolism
• at E11.5
• at E15.5 in the spinal cord region

nervous system
• prominent in the mesencephalic vesicle at E13.5, persisting at E15.5

skeleton
• in mice that survive beyond E16.5

muscle
• in the ventricles
• does not display organized clusters of smooth muscle cells or vascular structures unlike wild-type myocardium
• reduced trabeculation, thinner compact myocardium and disorganized ventricular myocardium
• reduced myocardial cytokinesis

craniofacial
• in mice that survive beyond E16.5
