An unusual variant of blood group A.
A blood specimen from a forensic science case appeared to violate Landsteiner's Rule. The red cells failed to react with anti-A, anti-B, or O serum while reacting strongly with Ulex europaeus lectin but not other anti-A lectins. The saliva from the person involved was found to contain both A and H blood group substances in a ratio of 4:1. The blood group was determined to be type Am.
