Moderate AD samples had significantly elevated levels events labeled with antibodies against Aβ42 (P = 0.0029), p‐tauS202‐T205 (P < 0.0001), p‐tau181 (P = 0.0003), p‐tau217 (P = 0.0036), p‐tauS235 (P = 0.0274), oligomeric amyloid (P < 0.0001), alpha‐synuclein (P = 0.0082), ubiquitin (P = 0.0050), and LAMP1 (P = 0.0067). This evidence concerns the gene SNCA and Alzheimer disease.
