Furthermore, mutations in genes encoding stress granule RNA-binding proteins including TAR-DNA binding protein (TDP-43), fused in sarcoma/translated in liposarcoma (FUS/TLS), heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1), and T cell-restricted intracellular antigen-1 (TIA-1) have been found in ALS/FTD patients pointing to direct link between abnormal regulation of stress granule formation in these neurodegenerative disorders (Benajiba et al., 2009; Kwiatkowski et al., 2009; Pesiridis et al., 2009; Gendron et al., 2013; Kim et al., 2013; Mackenzie et al., 2017). The gene discussed is HNRNPA1; the disease is amyotrophic lateral sclerosis.
