Scientists Discover 47th Blood Group System After 50-Year Mystery

Scientists have identified the 47th blood group system, known as the Mal blood group, which categorizes blood based on tiny markers on red blood cells. This discovery sheds light on the specific marker called the AnWj antigen, previously misunderstood for decades.

The antigen acts as an identification tag on blood cells, signaling the immune system. The Mal protein is responsible for creating the mysterious AnWj antigen, making it a significant breakthrough in understanding blood group systems.
