Both environmental and genetic factors are involved in the development of PD and biotransformation of exogenous and endogenous compounds and may play a role in inter-individual susceptibility. Therefore, we investigated the presence of null genotypes of GSTM1, GSTT1, and two polymorphisms of mEPHX in subjects with Parkinson's disease and in a reference population. The study included 35 male PD patients and a male control group including 283 subjects. Homozygosity of the histidine (H) 113 isoform of mEPHX was significantly increased in PD patients (odds ratio = 3.8 CI 95% 1. 2-11.8) and analysis of allele frequencies displayed an increased frequency of the H-allele among PD patients (odds ratio = 1.9 CI 95% 1.1-3.3). However, a significantly elevated median age for the onset of PD was found among GSTM1 gene carriers (median age = 68 years) compared to PD patients being GSTM1 null genotypes (median age = 57 years). Our observations suggest that (H) 113 isoform of mEPHX, which has been suggested as a low activity isoform, is overrepresented in PD patients and that inherited carriers of the GSTM1 gene postpone the onset of PD. These detoxification pathways may represent important protective mechanisms against reactive intermediates modifying the susceptibility and onset of PD.
