SNCA and Parkinson disease: To gauge at which phase in the disease trajectory the two new Parkinson’s disease-linked miRNAs hsa-miR-132-3p/-5p and hsa-miR-129-5p show the strongest degree of differential expression, we assessed their association with α-synuclein and tau Braak staging in the brains of Parkinson’s disease patients (for the distribution of Braak and tau staging in the Parkinson’s disease brains, see Supplementary Table S1).
