Notes
This SNP is in the ABO gene, and is therefore potentially useful in determing blood group type, such as through the use of genosets. This particular SNP can be useful in determining whether an ABO type A allele is more specifically an A1 type allele or an A2 type allele. The more common allele (80% of A types on average) is A1, consistent with having a rs55964869(C) allele, with the rarer A2 allele encoded by rs55964869(T). However, the key defining characteristic between an A1 and an A2 allele is the presence or absence of a deletion based on SNP rs8176750.
