There are five main Rh red cell antigens—D, C, c, E, and e—that involve most clinically significant transfusion complications. These five are the focus of this article. Two separate genes for the Rh system are found on chromosome 1. One gene, RHD, encodes for the D antigen.

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. 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.Altın Kan Özellikleri. 0 rh-Null olarak isimlendirilen ve 2010 yılında tespit edilen bu kan grubu dünyada sadece 40-45 kişi de bulunduğu tespit edilmiştir.

If you test negative for the presence of the D antigen, you are Rh Negative. This is why Rh Negative is also often listed as Rh (D) negative or D negative.
