| Webcontent | Mayo Medical LaboratoriesCopyright Copyright © 1995-2009 | There are presently 46 Rh antigens identified and named. The following are the most common of those variants: • Cw is a low frequency antigen found in approximately 2% of Whites and 1% of Blacks. It is not an allele of C and c. Its allele is MAR, which is found in 99.9% of the population. • V and VS are low frequency alleles found in 1% or less of the Whites, but are more common in Blacks. V is found in 30% of the Blacks and VS in 32%. • G is present when D or C present due to the present of serine at the 103 position of the Rh polypeptide. Anti-G will react with both D+ and C+ cells. • f is present when c and e together on same chromosome: Dce or ce. This is the most common of what are called cis product antigens. • Rh null has no Rh antigens on their red cells but these individual can transmit normal Rh antigens to their offspring. In the most common type the core Rh polypeptide is missing. A less common type has the regulator gene that turns off the expression of Rh. There have been at least 43 individuals in 14 families that are Rhnull. In these individuals the red blood cell membrane is abnormal and some of these have been identified when it was observed that they had hemolytic anemia and abnormal red cell morphology. If these individuals develop an Rh antibody following a transfusion or pregnancy, it is considered a anti-total Rh antibody. Rh Blood Group System - Other Rh System Variants |
