Well-known PD-related proteins, including PARK7 (β = −0.14, P = 2.7 × 10−23), PRKN (β = −0.09, P = 6.4 × 10−3), LRRK2 (β = −0.13, P = 2.7 × 10−4), FOXO3 (β = −0.05, P = 2.2 × 10−2) and SNCA (β = 0.05, P = 2.5 × 10−2), were also associated with PD. This evidence concerns the gene FOXO3 and Parkinson disease.
