For instance, Benigni et al., dichotomized ALS into C9orf72 expansion carriers (n = 8) and non-carriers (n = 16), analyzing a pattern of eight miRNAs from CSF (hsa-let-7a-5p, hsa-let-7b-5p, hsa-let-7f-5p, hsa-miR-15b-5p, hsa-miR-21–5p, hsa-miR-148a-3p, hsa-miR-181a-5p, and hsa-miR-195–5p). The gene discussed is C9orf72; the disease is amyotrophic lateral sclerosis.
