A person in the golden blood group lacks all Rh antigens, whereas a person in the Rh-negative blood group lacks only RhD antigens. If the protein is present, meaning the blood is Rh+, when blood is given to someone Rh-, the recipient's immune system will identify the protein as dangerous and create antibodies against it. The Hh blood group contains one antigen, the H antigen, which is found on virtually all RBCs and is the building block for the production of the antigens within the ABO blood group. H antigen deficiency is known as the "Bombay phenotype" (h/h, also known as Oh) and is found in 1 of 10,000 individuals in India and 1 in a million people in Europe. Variation causing blood group polymorphisms can be based on a variety of different genetic mechanisms [5, 14]. The majority of blood groups are induced by SNPs (e.g. k/K, Kp b /Kp a , Js a /Js b ). Single nucleotide exchanges in the genes either cause immunogenic amino acid substitutions in proteins that directly define the blood groups or they ...The Rh blood group system consists of 49 defined blood group antigens. One of them is the D antigen. If you test negative for the presence of the D antigen, you are Rh Negative. This is why Rh Negative is also often listed as Rh(D) negative or D negative.
