With the list of 49 proteins elevated, we observed a significant association using DAVID for the Parkinson’s disease (HTRA2, SDHA, NDUFS5, NDUFA10) and metabolic (SDHA, PIK3C3, RRM2, GNPDA2, CYP51A1, NDUFS5, TYMS, IMPA1, NDUFA10, PDXK) KEGG pathways. This evidence concerns the gene CYP51A1 and Parkinson disease.
