    The GGCC repeat expansion of the first intron of C9orf72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), accounting for 38% and 25% of familial cases, respectively


    Therapies targeting C9orf72 repeat expansions such as small molecules, 12 antisense oligonucleotides (ASOs), 13–18 siRNAs, 19 microRNAs, and CRISPR-based approaches are rapidly developing


    Glycoprotein levels in immune CSF were not found to correlate with clinical disease markers or neurofilament CSF levels, which are non-disease-specific biomarkers of neurodegeneration

    The mean value of the C9orf72 samples was 38-fold higher than that of the control group, both below the lower limit of quantification of the analysis


    C9orf72 amplifies glycan protein levels in the cerebrospinal fluid of carriers

    Compared with presymptomatic carriers, symptomatic carriers had higher than average poly(GP) levels, but this difference was not significant
