CTSC and frontotemporal dementia: We first evaluated the SNPs in TMEM106B (Van Deerlin et al., 2010) and those identified in the recent international FTD-GWAS for RAB38, CTSC, and the HLA locus (Ferrari et al., 2014); then we assessed the markers defining the C9orf72 (van Es et al., 2009), MAPT (Höglinger et al., 2011), and TOMM40/APOE (Seshadri et al., 2010) loci.
