    Study Notes

    The Rhesus (Rh) Blood Group System Lecture

    • The Rh blood group system has over 45 antigens, making it the most complex system.
    • The Rh genetics are controlled by autosomal codominant genes located on the short arm of chromosome 1.
    • The D antigen is present in 85% of individuals, while the d antigen is present in 15%.
    • The C antigen is present in 70% and the c antigen is present in 80% of individuals.
    • The E antigen is present in 30%, while the e antigen is present in 98% of individuals.
    • The presence or absence of the D antigen determines if an individual is Rh+ or Rh-.
    • There are four different nomenclatures for the Rh system: Fisher-Race, Wiener, Rosenfield, and ISBT.
    • The Fisher-Race theory has three closely linked loci, while the Wiener theory has only one gene locus with multiple alleles.
    • The Rosenfield nomenclature assigns each antigen a number.
    • The D antigen is extremely immunogenic and can cause severe hemolytic disease of the newborn.
    • Weak D phenotype occurs in some individuals and requires further testing to determine the D status.
    • Rh antibodies result from exposure to Rh antigens and can cause hemolytic transfusion reactions and hemolytic disease of the newborn.
