CD240CE
- Also called RH 30 CE, Rh blood group Cc and Ee blood group antigens; encodes RhC and RhE antigens on a single polypeptide
- On #1p36.11 adjacent to RH D gene
- Rh (rhesus) blood group system is second most clinically significant blood group after ABO; is most polymorphic blood group, with variations due to deletions, gene conversions and missense mutations
- Rh antigens are carried by an oligomer of two major erythroid specific polypeptides, the Rh (D and CcEe) proteins and the RhAG glycoprotein
- Rh proteins form a core complex critical to structure of erythrocyte membrane (Blood Rev 2006;20:93)
- May play a role in ammonia transport (J Biol Chem 2002;277:12499, Transfus Clin Biol 2006;13:132)
- Discrepant or doubtful serologic results can be resolved by sequence specific primer (PCR SSP) technique (Transfusion 2007;47:54S)
- Rarely causes hemolytic disease of newborn (Transfus Med 2000;10:305)
- Uses by pathologists: blood typing
- Positive staining - normal: erythroid cells
- References: Blood 2000;95:375, OMIM 111700
CD240D
- Also called RH30 D, Rh blood group D blood group antigen; is major antigen of the Rh system
- On #1p36.11 adjacent to RHCE gene
- Rh (rhesus) blood group system is second most clinically significant blood group after ABO; is most polymorphic blood group, with variations due to deletions, gene conversions and missense mutations
- Weak D, formerly called D(u), occurs in 0.2 to 1% of whites
- Exhibits reduced expression of D antigen (Blood 1999;93:385)
- Should not be labeled as Rh negative (Curr Opin Hematol 2006;13:476)
- Individuals are classified as Rh positive or negative based on presence or absence of highly immunogenic D antigen on red cell surface
- May have arisen historically by duplication of RHCE gene (Blood 2002;99:2272)
- Discrepant or doubtful serologic results can be resolved by sequence specific primer (PCR SSP) technique (Transfusion 2007;47:54S)
- Hemolytic disease of fetus and newborn: usually due to Rh negative woman whose partner is Rh+ or heterozygous and fetus is Rh+; woman has preexisting anti-RhD antibodies that cross placenta and harm fetus (Immunohematol 2006;22:188)
- Can use maternal plasma in alloimmunized pregnancies to determine fetal RhD status or for RHD and RHCE genotyping (Fetal Diagn Ther 2006;21:404, Prenat Diagn 2005;25:1079)
- Genotyping from amniotic fluid or chorionic villi sampling was performed in past but is more invasive (N Engl J Med 1998;339:1734, Clin Exp Med 2002;2:77)
- Rh positive mothers may rarely (0.15%) develop new antibodies (other than anti-RHD) in third trimester but no clinical significance (J Matern Fetal Neonatal Med 2007;20:59)
- Having Rh negative mother may be risk factor for autistic children, due to use of mercury containing Rho-immune globulin (J Matern Fetal Neonatal Med 2007;20:385)
- Uses by pathologists: blood typing
- Positive staining - normal: erythroid cells
- References: OMIM 111680, Wikipedia, eMedicine (Rh incompatibility)
