CYP2E1 and Parkinson disease: Results for CYPs showed that individuals simultaneously carrying the rs12441817/CC (CYP1A1), rs762551/AA (CYP1A2), and rs2070676/GG + GC genotypes (CYP2E1) were more resistant to PD susceptibility (P = 0.002, OR = 0.354, 95% CI = 0.184–0.682), while simultaneous presence of the rs12441817/CC and rs2070676/GG + GC genotypes appeared to play the core protective effect (P = 0.002, OR = 0.393, 95% CI = 0.216–0.715; Table 3).
