Alteration in cellular constituents and level of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) due to increased oxidative stress results in chronic kidney disease (CKD) and liver disease, which are among the major causes of morbidity and mortality worldwide and raise serious public health concerns [1,2,3,4]. The gene discussed is CAT; the disease is liver disorder.
