CHMP2B cases show downregulation in multiple transcripts encoding proteins involved in the transport of cargoes along microtubules, suggesting impairments in axonal transport (KIF1A, KIF1C, KIF5C DYNLRB1, DYNLL2 and DYNC1H1), a phenomenon that has been well documented in multiple neurodegenerative diseases, including a SOD1-mediated model of ALS [55]. This evidence concerns the gene KIF1C and amyotrophic lateral sclerosis.
