The ABO gene encodes the glycosyltransferase protein which is best known for ultimately determining blood type, otherwise known as the ABO blood group. SNPs in this gene determine whether an individual is of blood group type A, B, AB, or O. Determination of an individual's blood type based on SNPs can be done via genosets, but this remains a work in progress.
