Myeloperoxidase (MPO) has been shown to contribute to several diseases and more particularly to atherosclerosis through excessive ROS production via the MPO/H(2)O(2)/Cl(-) oxidation system. The aim of this study was to determine whether there is an association between MPO polymorphisms and brain infarction (BI), one of the main consequences of atherosclerosis. We investigated MPO G-463A and G-129A polymorphisms in 450 patients with BI confirmed by magnetic resonance imaging (MRI) and 450 controls of the GENIC (Génétique de l'Infarctus Cérébral) Study. Genotype determination of MPO was performed by polymerase chain reaction and allele-specific oligonucleotide hybridization (ASO). Genotype distributions for each of both MPO polymorphisms were found to be similar between cases and controls overall, and according to etiologic subtypes or gender. The frequency of the A allele of the G-463A polymorphism was 22% (95% confidence interval, 19.4 to 24.9) and the frequency of the A allele of the G-129A polymorphism was 6.8% (95% confidence interval, 5.3 to 8.6). The odds ratio (OR) for BI in carriers of the A allele of the G-129A polymorphism was 0.92 (95% confidence interval, 0.61 to 1.39), and the OR for BI in carriers of the A allele of the G-463A polymorphism was 1.15 (95% confidence interval, 0.88 to 1.52). No association between the main risk factors for BI such as hypertension, cholesterol, diabetes and MPO polymorphisms was found. In analyses restricted to cases, we identified an association between the A allele of the G-129A polymorphism and the size of the brain infarct (P=0.01). Furthermore, the A allele of the G-463A polymorphism was associated with a poorer functional short-term outcome as evaluated by the Rankin score (P=0.02). In conclusion, MPO polymorphisms were associated with the extent of brain damage and the functional outcome rather than with the risk of developing a BI.
