Less common mutations in other genes encoding TAR DNA binding protein 43 (TDP-43; TARDBP) [19, 32, 95], sequestosome-1/p62 (SQSTM1) [67, 121], charged multi-vesicular body protein 2b (CHMP2B) [104, 120], valosin-containing protein (VCP) [45, 126], TANK-binding kinase 1 (TBK1) [33, 38, 92], among other rare genes can cause FTD [44]. Here, VCP is linked to frontotemporal dementia.
