Over 150 mutations in the superoxide dismutase 1 (SOD1) gene have been associated with amyotrophic lateral sclerosis (ALS), but the disease-causing mechanisms are still being elucidated. Previous studies demonstrated SOD1 aggregates in motor neurons from patients with SOD1-ALS, and new research shows that misfolded mutant SOD1 protein can induce misfolding of the wild-type protein, thereby enabling propagation of SOD1 aggregates via a prion-like mechanism.
