Alone in the universe: Scientists discover new blood type unique to one woman
French researchers have discovered the 48th blood group system.
The discovery of a blood type unique to one woman is a reminder to think beyond the familiar ABO and Rh types.
Researchers in France announced last month they had identified a new blood type belonging to the new PIGZ blood group, unique so far to one woman from the French Caribbean island of Guadeloupe.
The woman, 68, was found to have a mutation in her PIGZ gene that impacted how certain proteins bind to her red blood cells.
This means no other person has blood compatible with hers, even universal donors.
