Semi‐quantitative analysis revealed no significant difference in the scores for neuronal LC3A immunostaining between FTLD (collectively), AD and controls (DG, H = 0.39, P = 0.820; CA4, H = 0.94, P = 0.626; Tcx, H = 2.6, P = 0.271), or between any of the five FTLD histological (DG, H = 7.3, P = 0.119; CA4, H = 1.9, P = 0.753; Tcx, H = 7.7, P = 0.103) or four genetic (DG, H = 0.147, P = 0.986; CA4, H = 0.790, P = 0.852; Tcx, H = 1.86, P = 0.602) groups. Here, MAP1LC3A is linked to Alzheimer disease.
