C9orf genetic testing
WebSep 19, 2024 · Eventually the responsible mutation was discovered to be in the C9orf72 gene, and this is now known to be the most common genetic cause of ALS. Since the mutated gene produces toxic products, blocking the gene with gene therapy might be a useful approach to treatment.
