Criteria | Gs131/criteria |
This genoset defines one of the ABO blood group types, that of type B blood.
From a molecular point of view, there are 2 B types: BB, and BO, based on whether the individual is carrying two type B alleles or one type B allele plus one type O allele. This genoset defines the most common type of BB carrier.
The criteria is based on SNPs rs8176746 and rs8176747, which for a (single) type B allele, will be rs8176746(A) and rs8176747(C).
Therefore, an individual will be an ABO type BB if they are not carrying a type O allele (i.e. not carrying a rs8176719(-) allele), and if they are either rs8176746(A;A) or rs8176747(C;C).
