Furthermore, we found no significant difference in the nucleocytoplasmic ratio of the RNA editing protein ADAR2, which has recently been shown to be mislocalized to the cytoplasm of C9orf72 ALS/FTD iPSC motor neurons, as well as in neurons in C9orf72 ALS/FTD postmortem tissues and C9orf72 ALS/FTD mouse model brain tissues (Moore et al., 2019). Here, C9orf72 is linked to amyotrophic lateral sclerosis.
