Abstract excerpt

INTRODUCTION: Bombay (Oh) blood group individuals are typically transfused with Bombay group red blood cells because transfusion with other blood groups can lead to life-threatening hemolysis. The mutations in the FUT1 gene prevent the expression of the H antigen on red blood cells. METHODS: A 35-year-old man presented with severe anemia (hemoglobin, 4.8 g/dL) and was transfused with 3 units of O RhD-positive...
