C9orf72 and amyotrophic lateral sclerosis: To further assess the relevance of our findings, we compared our data with a previously published dataset obtained from post-mortem spinal cord specimens from 57 neurologically healthy individuals and 214 ALS patients from the NYGC ALS cohort (n = 161 non-genetic ALS, n = 36 C9orf72, n = 5 SOD1, n = 2 FUS, and n = 10 with mutations in 8 other ALS genes), available on the database by Ziff and colleagues49 queried above.
