Rh (Rhesus) null hemolytic anemia (RHN) is a rare autosomal recessive disorder characterized by an absence of Rh antigens and a varying degree of hemolytic anemia and spherostomatocytosis. The Rh protein family comprises Rh50 glycoprotein and Rh30 polypeptides, which form a complex essential for Rh antigen expression and erythrocyte membrane integrity. It is reported that RHN is caused by mutations of RHAG that encodes Rh50 glycoprotein.
