mortality/aging
• double homozygotes exhibit the same abnormalities as single homozygous Nog mutants

nervous system
• abnormalities is neural tube closure, particularly in the brain vesicles between the diencephalons and myelencephalon
• in mutants where the frontal, parietal and interparietal bones are absent, the brain is exposed at birth

skeleton
• fusion of presphenoid, basisphenoid, and basioccipital bones
• frontal bone is loose or absent
• interparietal bones are loose or absent
• occipital condyles are loose, showing variability in the distance separating them
• parietal bone is loose or absent

limbs/digits/tail
• truncated limbs

craniofacial
• fusion of presphenoid, basisphenoid, and basioccipital bones
• frontal bone is loose or absent
• interparietal bones are loose or absent
• occipital condyles are loose, showing variability in the distance separating them
• parietal bone is loose or absent

embryo
• abnormalities is neural tube closure, particularly in the brain vesicles between the diencephalons and myelencephalon
