OMIA 000117-9940 : Blood group system A in Ovis aries
In other species: chicken , goat , pig , , aoudad , turkey , cattle Mendelian trait/disorder: yes Considered a defect: yes Key variant known: no Cross-species summary: Each blood group system consists of a set of blood types, each of which corresponds to a particular antigen (usually a glycoprotein) on the surface of red blood cells. The different types within a system are the result of the action of different alleles at a locus that usually encodes an enzyme that catalyses the creation of the feature of the glycoprotein unique to that type, e.g. the presence of a particular sugar at the end of a short chain of sugars. Species-specific description: This locus has at least 3 alleles.
