Antibodies against<unk>  system antigens can be stimulated by pregnancy or blood transfusion and have the potential to cause severe hemolytic disease of the fetus and newborn and acute hemolytic transfusion reactions. In red blood cells, the<unk>  antigen protein seems to play a role in adenosine transport in cell differentiation, when immature cells become red blood cells. Individuals with the null phenotype, lacking any form of the transporter protein, have mineralization around the joints, ectopic calcification, and abnormal red blood cells.
