TARDBP and amyotrophic lateral sclerosis: Alongside differential gene expression changes, RNA‐seq analysis has determined an enrichment in repetitive element (RE) transcripts following TDP‐43 knockdown, including MER21B, a RE increased in ALS patient post mortem brain samples (Prudencio et al., 2017), potentially due to changes in RNA polymerase II (LaRocca et al., 2019).
