(A transfusion of normal group O blood can trigger a severe transfusion reaction.). Because the H antigen is the precursor of the ABO blood group antigens, if it is not produced, the ABO blood group antigens are also not produced.f a person has blood group O, the H antigen remains unmodified. Therefore, the H antigen is present in the highest amounts in blood type O and in the least amounts in blood type AB. Two regions of the genome encode two enzymes with very similar substrate specificitiesâthe H locus (FUT1) and the Se locus (FUT2).
