Golden blood group, also known as Rhnull blood type, is an extremely rare blood type characterized by the absence of all Rh antigens, including the D antigen, which is the most common one. Individuals with this blood type are sometimes referred to as "universal donors of the rare blood types" because their blood can be safely transfused …The most common blood type is O positive. There are four blood group types: A, B, AB and O. These groups are determined by the presence or absence of two antigens, A and B, on the ...A person in the golden blood group lacks all Rh antigens, whereas a person in the Rh-negative blood group lacks only RhD antigens. If the protein is present, meaning the blood is Rh+, when blood is given to someone Rh-, the recipient's immune system will identify the protein as dangerous and create antibodies against it.Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.

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.The donor subject had been previously identified as a homozygous carrier of the c.836G > A single‐base mutation in the RHAG gene, leading to the rare Rh null blood type. 27 , 28 , 29 The Rh‐blood group deficiency, or Rh null, is an extremely rare phenotype which lacks all the Rh antigens on the red cell membrane.The blood, known as Rhnull (or Rhesus null), is often referred to as "golden blood" due to its rarity and great value.

It is characterized by the weak (Rhmod) or lack (Rhnull) of expression of all Rh antigens on the red cells.Rhnull blood was first discovered in 1961 in an Aboriginal Australian woman.
