WebAbstract. Numerous studies have shown that the antigenic determinants of the ABO blood group system are closely related in biochemical terms to the antigenic determinants of the Hh, P, Lewis and Ii blood group systems. The blood group antigens of each of these systems are formed by the addition of specific sugars to an oligosaccharide precursor ...

WebThe expression of ABO blood group antigens is determined by the interaction of three genes: the ABO gene, which controls expression of the A and B antigens; the FUT1 or H gene, which controls expression of the H antigen, the precursor of ABO antigens; and the secretor gene, FUT2 or Se. WebThe associated anti-A and anti-B antibodies are usually IgM antibodies, produced in the first years of life by sensitization to environmental substances such as food, bacteria, and viruses. The ABO blood types were discovered by Karl Landsteiner in 1901; he received the Nobel Prize in Physiology or Medicine in 1930 for this discovery. [5]
