Myeloperoxidase (MPO) catalyses the formation of hypochlorous acid and is involved in many (patho)physiological processes. The present study was designed to determine the effect of two MPO promoter polymorphisms (463G/A and 129G/A) on enzyme activity. In 243 healthy controls, genotypes were determined and MPO activity was measured on a single-cell level using a haematological analyser. The 129G/A polymorphism reduces MPO activity in neutrophils, whereas for the 463G/A polymorphism, only gender-dependent differences in MPO activity in older age groups could be found. When studying these polymorphisms in disease, therefore, age and gender should be included in the analysis.
