Introduction. Nearly a century after the first publications which would lead to the recognition of the Rh blood group system (1,2), and 40 years after the molecular basis of the Rh antigens (Ag) were discovered (3,4), 55 Rh Ag, over 400 RHD and over 150 RHCE alleles are recognized by the International Society of Blood Transfusion (ISBT) (). The Rh blood group system is the most complex blood group system known. 1 Currently, 48 antigens are distinguished. Even this number does not fully reflect the serologic diversity of the Rh blood group, because this list of antigens disregards the complexity of the D antigen revealed by monoclonal antibodies binding to different epitopes 2,3 and by the anti-D formed in carriers of partial D ...

The Rh deficiency syndrome, also known as Rh-null syndrome, is a blood disorder where people have red blood cells (RBCs) lacking all Rh antigens. The Rh antigens maintain the integrity of the RBC membrane and therefore, RBCs which lack Rh antigens have an abnormal shape. There are two types of Rh deficiency syndrome: [10568]Rh null. The lack of both RhD and RhCE proteins may be caused by the inheritance of two nonfunctional RHCE alleles in the background of an RHD deleted haplotype.
