Mendelian trait/disorder: yes

Considered a defect: no

Key variant known: no

Cross-species summary: N-glycolylneuraminic acid (NeuGc), a sialic acid involved in cell-cell recognition and cell-pathogen interactions, is abundantly expressed in most mammals but is not detectable in humans. The synthesis of NeuGc is controlled by cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) activity. The enzyme CMAH is inactivated in humans by a deletion.

Species-specific description: This phene includes references to studies involving genetically modified organisms (GMO).
