Quinone oxidoreductase (NQO1), a potent antioxidant system, its expression levels are prominently increased in the early and intermediate stages of PD and disappeared in the end-stage PD.
Moreover, among subjects exposed to pesticide, the combined MnSOD/NQO1 variant genotype was significantly associated with a 4.09-fold increased risk of PD (95%CI, 1.34-10.64, P=0.0052).

We investigated associations of genetic polymorphisms of NQO1 (C609T) and NQO2 (I/D, 29 base pairs) with PD in a population-based case-control study of 190 idiopathic PD cases and 305 unrelated controls matched on age and sex.
