Conversely, proteins that differed significantly between AD/PD and NC in the Emory study included only 6 proteins that also appeared significant in our comparisons: tau, 14‐3‐3γ, HSPβ‐1, peroxiredoxin‐2, required for meiotic nuclear division protein 1 (RMND1), and pyridoxal phosphate phosphatase (PDXP). This evidence concerns the gene PDXP and Parkinson disease.
