Additionally, a subset of studies investigated other ALS-FTD-related genes, including superoxide dismutase 1 (SOD1) (Kim et al., 2020; Mithal et al., 1999; Martin et al., 2007; Penndorf et al., 2017; Karanjawala et al., 2003), Senataxin (SETX) (Richard et al., 2020; Cohen et al., 2018), Heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) (Lee and Rio, 2024), and Vps54 (Junghans et al., 2022) although each in only a small number of studies. This evidence concerns the gene VPS54 and frontotemporal dementia.
