Specifically, PROT‐a‐1783 (LRPPRC), PROT‐a‐1864 (MCEE), and PROT‐a‐1970 (MUL1) showed notable associations with PD (IVW: OR = 1.1227, 95% CI 1.0306–1.2231, p = 0.008; IVW: OR = 1.2463, 95% CI 1.0608–1.4643, p = 0.0074; IVW: OR = 1.1633, 95% CI 1.0257–1.3193, p = 0.0185). Here, MUL1 is linked to Parkinson disease.
