Sod2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
SOD2 (Superoxide Dismutase 2) encodes the mitochondrial manganese superoxide dismutase, a critical antioxidant enzyme that protects mitochondria from oxidative damage. SOD2 mutations are associated with rare forms of ALS, and common variants may influence neurodegenerative disease risk. [@tsang2019]
Overview
The SOD2 (Superoxide Dismutase 2) gene encodes the mitochondrial manganese superoxide dismutase, a key antioxidant enzyme that scavenges superoxide radicals in mitochondria. SOD2 protects cells from oxidative stress and mitochondrial dysfunction, both of which are central to neurodegenerative processes. SOD2 polymorphisms are associated with increased risk for Alzheimer's and Parkinson's diseases. [@liu2018]
