Overview
SOD2 Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems. Genetic variation in SOD2 is associated with susceptibility to microvascular complications of diabetes type 6 (MVCD6). These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new- onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Belongs to the iron/manganese superoxide dismutase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
