Bioprocess enrichment analysis identified adherens junction organization as the most over-represented biological process, representing a total of 6 proteins that were decreased in PD relative to HC: cadherins 2, 6, 8, 10 and 13 (CDH2, CDH6, CDH 8, CDH10 and CDH 13), and cell adhesion molecule 2 (CADM2). This evidence concerns the gene CDH10 and Parkinson disease.
