Background. We recently encountered a Rh null phenotype proband within one family in the Chinese population. Rh null is a rare autosomal recessive disorder characterized by the absence of the Rh antigens on the erythrocyte membrane, resulting in chronic hemolytic anemia. This study described the serological and molecular analysis …One of them is the D antigen. 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. If you test negative for the presence of ALL antigens of the Rh Blood Group System, you are RHnull.Like I mentioned earlier, Rh factor is short for Rhesus factor. This actually refers to how scientists first discovered Rh: in Rhesus macaque monkeys. Other primates have similar Rh molecules to us. And if you go even further back in evolutionary history, you can even find similar genes in bacteria! 2. Humans have two different Rh genes: RHD ...Rh-defiency syndrome results from the lack (Rh null ), or severe reduction (Rh mod ), of Rh blood-group antigens, and was first described 40 years ago.
