SOD3 and coronary artery disorder: The present study, therefore, aimed to evaluate the associations of individual and combined SOD2, SOD3, GPX3, and GSTT1 gene polymorphisms with lipid abnormalities, particularly HTG and low HDL-C level in subjects with high risk of CAD, and to further investigate the associations of these polymorphisms and lipid abnormalities with the severity of coronary atherosclerosis.
