A systemic prooxidant status in DS individuals has been confirmed in various studies that demonstrated an increased activity of some important antioxidant enzymes (SOD1, CAT, and GR) together with decreased glutathione (GSH) levels in DS whole blood and higher levels of biomarkers of oxidative damage, such as protein carbonyls, malondialdehyde (MDA), allantoin, or 8-hydroxydeoxyguanosine than in controls [35]. The gene discussed is SOD1; the disease is Dravet syndrome.
