The odds of lacking every single antigen from the largest blood antigen group in the body are so low that less than 50 people in the world have this blood type.Background: The deficiency of Rh proteins on red blood cells (RBCs) from individuals of the Rh(null) amorph type are the result of homozygosity for a silent RHCE in cis with a deleted RHD. A novel mutation in RHce was identified in two Caucasian Brazilian girls with the amorph type of Rh(null) who were born to parents who were first cousins.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. The clinical, haematological, and biological abnormalities associated with this rare disorder indicate that it affects the membrane integrity of red blood cells.Humans have four different blood types: A, B, AB and O. Each of these blood types is also labeled positive or negative, depending on whether the red blood cells carry the Rh factor...

O negative blood group is a type of blood group that does not have any of the major blood group antigens (A, B, or Rh).

Rh-Null, Amorph Type. The Rh-null phenotype is of 2 types. The most common type, called the 'regulator type,' occurs by an inhibition mechanism; see RHNR, 268150.This form is caused by homozygosity for an autosomal recessive suppressor gene that is genetically independent of the Rh locus, mapping to chromosome 3 rather than to chromosome 1. これらの型のうちRh null型以外は定義上Rh + 型になるが、実際は普通のRh + 型を輸血すると、−D−型は自己が持たないC (c) やE (e) 抗原と反応してしまい、Partial D型などはDの不足分に自己にない抗原があるので輸血不可になる。 Rh null individuals have no Rh antigens (no Rh or RhAG) on their red blood cells. This rare condition has been called “Golden Blood”.As a consequence of Rh antigen absence, Rh null red blood cells also lack LW and Fy5 and show weak expression of S, s, and U antigens.

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 ...Each of the common blood types—A, B, AB, and O—comes in negative and positive versions (depending on whether or not red blood cells have a protein called an Rh antigen on their surface).
