Single-gene trait/disorder: unknown

Disease-related: 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 summary: There are seven major equine blood group systems (A, C, D, K, P, Q, and U) recognized by ISAG (Sandberg and Cothran 2000).
