Rh Null Phenotype
Rh null individuals have no Rh antigens (no Rh or RhAG) on their red blood cells. As a consequence of the absence of Rh antigens, Rh null red blood cells also lack LW and Fy5 and show weak expression of S, s, and U antigens.
Red blood cells lacking Rh/RhAG proteins have structural abnormalities (such as stomatocytosis) which can result in hemomlytic anemia.
