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. The ABO blood group system arises from two alleles at a locus that encodes a glycosyltransferase: the A allele encodes alpha 1-3-N-acetylgalactosaminyltransferase; and the B allele encodes alpha 1-3-galactosyltransferase. The B allele transferase catalyses the addition of galactose to a chain of four sugars attached to a protein known as H antigen. The A allele ltransferase catalyses the addition of a derivative of galactose called N-acetylgalactosamine to the same short chain of sugars. The third allele at this locus (the O allele) results in no sugar being added to the chain.

Molecular basis: Kitano et al. (2009) reported that the essential differences between the A and B alleles in this species are haplotypes arising from c.2178C>A and c.2185G>C, each of which is missense. Specifically, the A allele has haplotype c.2178C + c.2185G and the B allele has haplotype c.2178A + c.2185C.

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
