Abstract: Reactive oxygen species derived from dopamine metabolism can induce oxidative stress and thus may contribute to Parkinson's disease (PD) pathogenesis. The quinone oxidoreductases, nicotinamide adenine dinucleotide (phosphate) (NAD[P]H): quinone oxidoreductase 1 (NQO1) and dihydronicotinamide riboside (NRH): quinone oxidoreductase 2 (NQO2) detoxify quinones and quinonoid compounds. 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. No associations were detected for either gene variant or for any allele combinations.
