This is the first report of a family with several individuals with a FTD clinical phenotype and underlying co-pathologies of APBD, FTLD-TDP, and ARTAG with a segregating GBE1 loss-of-function mutation in affected siblings. The finding of co-pathologies of APBD and FTLD-TDP suggests these processes may share a disease mechanism resulting from this GBE1 mutation.
