SOD3 and myocardial infarction: Previously, Mohammedi et al. found an association between the promotor variant rs2284659 in the SOD3 gene, associated with higher plasma and presumably higher tissue levels of SOD3, and lower cardiovascular morbidity and mortality with a hazard ratio of 0·75 (95% CI: 0.59–0.94) for myocardial infarction and of 0.83 (0.69–0.99) for cardiovascular mortality in three prospective cohorts including 3921 type 1 and type 2 diabetic patients (Mohammedi et al., 2015).
