Association of SOD2 p.V16A polymorphism with Parkinson’s disease: A meta-analysis in Han Chinese
Background: Oxidative stress could participate in the pathogenesis of Parkinson's disease (PD). However, the role of genetic variation of superoxide dismutase 2 (SOD2), an important regulator against oxidative stress, in PD remains to be elucidated. Methods: We screened SOD2 gene variation by s...
