Our dementia group contained individuals with a diagnosis of an FTD syndrome, including those typically associated with FTLD-TDP or FTLD-tau (bvFTD, svPPA and nfvPPA) and those associated with AD pathology (lvPPA), which in theory could have differentially affected sTREM2 levels within the group as a whole. The gene discussed is MAPT; the disease is Alzheimer disease.
