    Abstract:
    We investigated the association of Parkinson's disease (PD) with two genes encoding liver-detoxifying enzymes, debrisoquine 4-hydroxylase (CYP2D6) and N-acetyltransferase 2 (NAT2), and with one gene related to Alzheimer's disease, apolipoprotein E (APOE). In a sample of 139 unrelated PD cases and 113 control subjects, the NAT2 M3 allele was associated with PD (odds ratio = 7.9; 95% confidence interval = 1.7-36.3). Case-control analyses for CYP2D6, APOE, and NAT2 M1 or M2 did not show a significant association. However, the age at onset of PD was significantly earlier in cases with the APOE epsilon2/epsilon3 genotype than in cases with the epsilon3/epsilon3 genotype.
