Several documented cases of glutathione peroxidase (GPX1; 138320) deficiency in association with hemolytic anemia have been reported. However, Paglia (1989) stated: 'To date, no defects in glutathione peroxidase have been unequivocally incriminated in the pathogenesis of hemolytic syndromes, although several instances of partial deficiency have been reported in patients with anemias of unknown etiology. This association may be coincidental, since there is a broad range of ethnic variation in the erythrocyte enzyme' (Beutler and Matsumoto, 1975). [from OMIM]
