The Hh blood group contains one antigen, the H antigen, which is found on virtually all RBCs and is the building block for the production of the antigens within the ABO blood group.

It is divided into the regulator and amorph types based on the underlying genetic background. The more common regulator type depends on critical variants silencing RHAG, which encodes RhAG glycoprotein, necessary for …Rh null. The lack of both RhD and RhCE proteins may be caused by the inheritance of two nonfunctional RHCE alleles in the background of an RHD deleted haplotype. This constellation gives rise to the amorph type Rh null phenotype (lack of any Rh protein), in which neither D nor CE antigens are expressed 54, 55.

Oct 1, 2021 · The lack of expression of the D antigen causes the Rh-negative phenotype. This phenotype is caused by three genetic mechanisms, including the complete deletion of the RHD gene, RHD pseudogene, and RHD-CE-D hybrid gene 7, 8. In white Europeans and Americans, the D-negative phenotype is caused by the complete deletion of the RHD gene. The Rh null phenotype is an inherited condition that may arise from homozygosity either for a ‘suppressor’ gene unrelated to the RH locus (‘regulator type’) or for a silent allele at the RH locus itself (‘amorph type’). A current model suggests that the proteins of the Rh complex (Rh, RhAG, CD47, LW, GPB) are assembled by non ...

It has no Rh antigens at all, known as Rh null. It is dubbed "golden blood" because it can be donated to people with almost any Rh blood type, including those with rare types of Rh antigens. However, if people with golden blood need blood, they can only receive the same type of blood ...People who have Rh- blood lack the D antigen, which is the most important in terms of determining donor-recipient matches, so more accurately they are RhD-. On the other hand, Rh(null) people have none of the Rh antigens, meaning that any blood they receive from the majority of donors would elicit an immune response.Rh-null occurs when a person’s blood lacks all of the 61 possible antigens. Because Rh-null lacks all of the possible antigens it can be donated to others who have highly unusual blood types outside of the main eight types. However, Rh-null can only accept blood from others with Rh-null.

Red blood cells that fail to react with all Rh antibodies are called Rh null. An individual’s genotype can only be determined with certainty by performing DNA analysis and family studies.
