The mean of the EIM change at 6 months of the ALS and ALS-FTD subpopulation (n=9)versus ASYMP (n=5) was significant (p=0.0339).Conclusions: Our exploratory assessment suggests that EIM maybe a useful technique to follow the progression of C9ORF72 subjects with ALS or ALS-FTD over time. Decrease in EIM over time could be used as a biomarker in ALS/ALS-FTD with the C9ORF72 genetic mutation.Study Supported by:This research was supported [in part] by the Intramural Research Program of the NIH, NINDSDisclosure: Dr. Offit, M.S. has nothing to disclose.
