Glucose 6 Phosphate Dehydrogenase Deficiency (G6PD Deficiency)

Date of Publication:



The most prevalent human enzyme deficiency, stemming from an intrinsic metabolic defect of red blood cells. Most people with G6PD deficiency are unaware of their status, living with no anemia, symptoms, or complications. The disorder becomes recognizable when exposure to oxidant drugs, infection, or ingestion of fava beans triggers an episode of acute hemolysis (rupture of red blood cells).
