New Blood Type Discovered in French Woman from Guadeloupe: “Gwada Negative”
French scientists have made a groundbreaking discovery by identifying a new blood type, “Gwada negative,” in a woman from Guadeloupe. This significant finding, announced by France’s blood supply agency on June 21, 2025, marks the 48th recognized blood group system globally.
The woman from the Caribbean island of Guadeloupe is the only known carrier of this new blood type, shedding light on the complexity and diversity of human blood.
This breakthrough, published in 2024, is a major milestone in the field of hematology. The discovery not only answers age-old questions but also opens the door to further understanding the intricacies of blood types and genetics.
The Genetic Breakthrough: Understanding the “Gwada Negative” Blood Type
A new study conducted by French researchers unveiled the unique blood type present in the woman from Guadeloupe. Known as “Gwada negative,” this blood type belongs to a rare group of blood types that challenge the conventional understanding of blood systems.
The research team also found similarities to another rare blood group, the MAL blood group, which showcases the impact of genetic mutations on blood characteristics. The absence of the AnWj antigen in the original patient highlighted the significance of genetic variations in defining blood types.
Unraveling the Complexity of Blood Genes
The discovery of the “Gwada negative” blood type emphasizes the importance of studying human blood from a genetic perspective. By exploring the role of mutations in blood genes like MAL, researchers can gain a deeper understanding of how blood types are determined and classified.
Moreover, this discovery offers insights into the diversity of human blood and the potential for identifying further unique blood types among populations worldwide.
In conclusion, the identification of the “Gwada negative” blood type in a French woman from Guadeloupe represents a significant advancement in the field of hematology. This breakthrough showcases the intricate relationship between genetics, blood types, and human health.
