More recently, mutations in hnRNPA1 have been reported in ALS [60], as well as in the RNA binding proteins TATA box binding protein associated factor 15 (TAF15) [61] and Ewing sarcoma breakpoint region 1 (EWSR1) [62], both of which belong to the same protein family as FUS. This evidence concerns the gene FUS and amyotrophic lateral sclerosis.
