From NCBI Gene:
The Rh blood group system is the second most clinically significant of the blood groups, second only to ABO. It is also the most polymorphic of the blood groups, with variations due to deletions, gene conversions, and missense mutations. The Rh blood group includes this gene which encodes both the RhC and RhE antigens on a single polypeptide and a second gene which encodes the RhD protein. The classification of Rh-positive and Rh-negative individuals is determined by the presence or absence of the highly immunogenic RhD protein on the surface of erythrocytes. A mutation in this gene results in amorph-type Rh-null disease. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms.

May be part of an oligomeric complex which is likely to have a transport or channel function in the erythrocyte membrane.

- RH-NULL, AMORPH TYPE
Rh-null, amorph type (RHNA): An autosomal recessive condition characterized by red blood cells that lack all Rh antigens, have increased osmotic fragility, diminished lifespan, and show changes in morphology resulting in stomatocytosis. Rh-null individuals have mild to moderate hemolytic anemia. They are at risk of having adverse reactions in response to transfusion or pregnancy, because they may produce antibodies against several of the Rh antigens. [MIM:617970]
