Thank you to Gordon Scherer for bringing the later to my attention. Source: H-deficient blood groups ( Bombay) of Reunion Island. Segregation of H and Se is compatible with the genetic model proposing that Se and H are closely linked structural genes, and the analysis of the present and previously published Bombay pedigrees strongly supports this model. In accordance with this concept, all the children from Bombay nonsecretor x unaffected nonsecretor matings were se/se. Fifty-three of the 108 (49%) unaffected members in the 14 Bombay pedigrees analyzed were se/se, showing that the families were selected for the nonsecretor trait, and suggesting that the Bombay probands used to select the families have se/se genotype.

All the H-deficient phenotypes tested were nonsecretors of ABH in their saliva, and one-third were Lewis negative.

A, B, and AB Bombay subjects had small but detectable amounts of A and/or B antigens on erythrocytes. On the island of Reunion, the frequency of Bombay blood is unusually high as well.įorty-two H-deficient individuals (lacking H antigen on erythrocytes) with anti-H in their sera were found on Reunion Island.

But there are a few places and populations among whom the frequencies are unusually high: The origin of Bombay blood has yet to be determined. (Read: Mangalore docs perform open heart surgery on woman with rare blood group) So transfusion of blood from people with blood group A, B, AB or O (which contains H antigens) will cause a reaction (acute haemolytic transfusion reaction) in the body leading to serious health complications. However, people with Bombay blood group do not have a H antigen meaning they have anti-a, anti-B and anti-H antibodies in their blood. Apart from A, B and O blood group, we also have an antigen known as H antigen. People usually have either of A, B, AB or O blood groups hich have H antigens. For example, a person with A blood group will have type A antigens and anti B antibodies (immune cells that fight against antigens other than their own antigens, in this case they produce antibodies against B). Bombay blood group is a type of blood group that has no ‘H’ antigen.
