In addition, we also focused our attention on investigating the differential expression of three intragenic miRNA host genes, including C1orf61 (miR-9), AATK (miR-338), and DNM2 (miR-638), which were thus examined, for the first time, in this study in connection with ALS. This evidence concerns the gene MIR9-1HG and amyotrophic lateral sclerosis.
