Consistent observations in the same line of FUS, also the ALS‐associated TDP‐43 protein was reported to be present in exosomes from primary neurons of human amyotrophic lateral sclerosis brains (Iguchi et al., 2016) and plasma of ALS patients (Sproviero et al., 2018). The gene discussed is FUS; the disease is amyotrophic lateral sclerosis.
