Four red cell antigens resulting from a single amino acid substitution form the RhAG blood group system.7, Red blood cells lacking all Rh antigens are designated Rhnull.8 Although exceedingly rare, the phenotype most often results from nucleotide changes in RHAG known as a regulator-type Rhnull, indicating that the RHAG protein plays a critical role in trafficking RHCE and RHD to the membrane, as was seen with the donor in this case.7 Less often, Rhnull individuals have RHCE nucleotide changes along with the common deletion of RHD, and these individuals are called amorphs.7, Common features of Rhnull RBCs are stomatocytes (Figure 2) and mild anemia, suggesting that the Rh proteins have an important structural role in the erythrocyte membrane.7 Other findings include spherocytosis, increased osmotic fragility, altered phospholipid asymmetry, altered cell volume, defective cation fluxes, and elevated Na+/K+ATPase activity.812 The Rh complex is associated with the membrane skeleton through CD47 protein 4.2, ankyrin band 3, Duffy, and glycophorin B and C interactions.13,14, Typical Rh antibodies do not activate complement.6 As a result, in a transfusion reaction involving Rh antibodies, hemolysis is primarily extravascular rather than intravascular.6 Although not relevant with this case due to the patients age, Rh antibodies have the potential to cause clinically significant hemolytic disease of the fetus and newborn.2 Antibodies to high-prevalence Rh antigens include anti-Rh29 made by some Rhnull individuals, including the patient in this case, who lacked Rh antigens.6, Rhnull RBCs have a shortened in vivo survival, and patients often demonstrate a compensated hemolytic anemia.15,16 Transfusion of patients with anti-Rh29 is a concern because only the Rhnull RBCs will be compatible.
