phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• males survive until birth but die on first postnatal day

cardiovascular system
• blood vessels in brain are dilated
• males show abnormal outflow tracts including interrupted aortic arch, but less severe than Flnatm1.1Caw mutant males
• some adherens junctions (AJs) are unidentifiable, with excessive membrane ruffles at sites where AJs normally form
• endothelial cells are poorly organized with clusters or multiple layers and gaps in outflow tract
• males show abnormal outflow tracts including PTA, but less severe than Flnatm1.1Caw mutant males
• endothelial cells are poorly organized with clusters or multiple layers and gaps in endocardial cushion

homeostasis/metabolism
• males are cyanotic at birth, indicating hypoxemia

nervous system
• at E14.5, surviving mutants have smaller but grossly normal brains, with thinner cortical plate

behavior/neurological
N
• no heterotopic neurons or migratory arrest are seen in mutant brains
