Ael Blood Group

Subject: Science & Tech

Context- According to pathologists, about 40 to 50 people in the world have Ael blood.

Concept-

According to pathologists, there are barely 40 to 50 people in the world with Ael blood group, most of whom are in South-East Asia.
Ael has the least amount of A antigen among A subgroups and can only be detected through special tests.
There are a few other rare blood groups and rare phenotypes reported from India many of which have been discovered among Gujaratis.
- Bombay group,
- Indian blood group phenotypes like In(a+), In(b-), In5- (INRA-), and
- other rare phenotypes like Colton-null, Emm-null, P- null, and Rh-null.

Rare Blood Groups:

The blood groups which are seen less in human population are said to be rare blood groups.
Among the various rare blood groups are Rh null, AB negative, A negative, B negative and AB positive.

The Bombay Blood Group:

The Bombay blood group (also called hh), is deficient in expressing antigen H.
It means the RBC of hh blood group has no antigen H.
Often the hh blood group is confused with the O group.
The difference is that the O group has Antigen H, while the hh group does not.
The rare Bombay blood group was first discovered in Mumbai (then Bombay) in 1952 by Dr Y M Bhende.
Globally, the hh blood type has an incidence of one in four million. However, this blood type is more common in South Asia than anywhere else because of inbreeding and close community marriages.
