Rhnull blood group.

The RH-null phenotype designates rare individuals whose red blood cells lack all Rh antigens. Two RH-null types, the regulator type (RHNR; 268150) and the amorph type (RHNA), arising from independent genetic mechanisms have been distinguished. The regulator type is caused by mutation in the RHAG gene (180297).
