Rhnull blood group.

Red cells lacking Rh blood group antigens were first described by Vos et al. (1961).Rh-null (no Rh antigen on the red cells) exists in 2 forms.

The Rh blood group antigens (D, Cc and Ee series) are carried by a family of non glycosylated hydrophobic transmembrane proteins of 30-32 kDa which are missing from the red cells of rare Rhnull individuals that express several membrane defects.

The rarest blood type in the United States, using the ABO and Rh classification groups, is AB negative, found in just 1% of the population.
