IDUA and Parkinson disease: Focusing on the GWAS meta-analysis top signals (Table 2), seven PD-associated SNPs were associated with a total of 163 proteins, including rs2230288, rs34311866, rs2760980, rs10847839, rs2183082, rs4630591, and rs6857, among which 4 SNPs were only associated with one protein including rs2230288-T (Ephrin, EFNA; P = 2.4E-10), rs34311866-C (Alpha-L-Iduronidase, IDUA; P = 4.6E-8), rs10847839 (Huntingtin-interacting protein 1-related protein, HIP1R; P = 6.7E-30), and rs2183082-T (Galectin-3, LGALS3; -log10(P) = 311.6).
