In an independent longitudinal proteomics dataset we replicated αSyn-induced increases among 6 of these proteins (S9 Fig), including Npc1a and several proteins homologous to human LSD gene products causing mucopolysaccharidoses: GLB1/Ect3, MAN2B1/LManII, and MANBA/Beta-Man. This evidence concerns the gene MAN2B1 and mucopolysaccharidosis.
