Consistent with our previous results, we observed significant differences between the sympAD and the FTD group regarding the prevalence of pTDP409/410 (p = 0.023), pTDP-43403/404 (p = 0.001), C- and N-t TDP-43 (p = 0.001), but not pTDP-43409 (Additional file 1-Tables A18-A22). The gene discussed is TARDBP; the disease is frontotemporal dementia.
