cardiovascular system
• 16 of 22 mice between E16 and E18 exhibit either ventricular septal defect (VSD), overriding aorta, double outlet right ventricle, or a combination of VSD and one of the other two defects unlike wild-type mice

craniofacial
• at E16, the roof of the mouth is wider than in wild-type mice
• at E13, the number of apoptotic cells is increased 2-fold compared to in wild-type mice likely as a secondary consequence to failure of palate shelf movement
• however, proliferation of cells during palate development is normal
• in nearly all mice

embryo
N
• mice exhibit normal dorsal root ganglia and thymic rudiments indicating normal neural crest migration
• mice do not exhibit neural tube defects

hearing/vestibular/ear
• mice exhibit cochlear hair cell defects (hair cell number and outer hair cell row 3 orientation) unlike wild-type mice
• most severe in outer hair cell row 3

homeostasis/metabolism
• at birth

nervous system
• mice exhibit cochlear hair cell defects (hair cell number and outer hair cell row 3 orientation) unlike wild-type mice
• most severe in outer hair cell row 3

digestive/alimentary system
