2025-06-21
A French woman from Guadeloupe has been identified as the sole known carrier of a new blood type, dubbed 'Gwada negative.' The discovery, officially recognized by the International Society of Blood Transfusion, was made possible by high-throughput DNA sequencing after an unusual antibody was detected in 2011. The woman inherited the mutated gene from both parents. This finding improves care for patients with rare blood types.
