mortality/aging

craniofacial
• malformations of cranial bones at E18

cardiovascular system
• abnormal branching of the left carotid artery from the brachiocephalic trunk in mutant mice
• venous congestion
• defective separation of the aorta from the pulmonary trunk, leading to persistent truncus arteriosis
• exhibit vasodilatation of the jugular veins
• heart defects lead to functional right-sided heart failure with venous congestion, resulting in a vasodilatation of the jugular veins

endocrine/exocrine glands
• 2 of 5 do not have parathyroid glands
• 3 of 5 exhibit hypoplastic parathyroid glands at E18
• thymus gland is 58% the size of wild-type at E18

immune system
• thymus gland is 58% the size of wild-type at E18

nervous system
• defect in neural crest cell differentiation in the pharyngeal apparatus but not in the migration or survival of neural crest cells
• absence of neural crest-derived smooth muscle cells
• midbrain abnormalities
• hindbrain abnormalities

skeleton
• malformations of cranial bones at E18
• malformation of cartilage at E18

hematopoietic system
• thymus gland is 58% the size of wild-type at E18

digestive/alimentary system

embryo
• defect in neural crest cell differentiation in the pharyngeal apparatus but not in the migration or survival of neural crest cells
• absence of neural crest-derived smooth muscle cells

muscle
• exhibit vasodilatation of the jugular veins
