The medical literature includes one reported case of putative microscopic DRG findings in a 22-year-old male with amyotrophic lateral sclerosis and mutations in the superoxide dismutase 1 (SOD1) gene who received a single intrathecal infusion of AAV-miR-SOD1 (4.2 × 1014 vg).48 However, the published information was limited, and the authors were not able to determine if the findings were because of gene therapy or the underlying disease state. Here, SOD1 is linked to amyotrophic lateral sclerosis.
