The unique blood of a woman from Guadeloupe has led to the identification of the Gwada-negative blood group, the world's newest and rarest blood group. Scientists found that her blood plasma reacted against every potential donor sample, leading them to discover a mutation in the gene PIGZ that creates a new antigen on red blood cells. This antigen change defines the new blood group classification, Gwada-positive or Gwada-negative.
