A frequent ala 4 to val superoxide dismutase-1 mutation is associated with a rapidly progressive familial amyotrophic lateral sclerosis

Abstract excerpt

Familial amyotrophic lateral sclerosis (FALS), a degenerative disorder of motor neurons, is associated with mutations in the Cu/Zn superoxide dismutase gene SOD1 in some affected families. We confirm a recently reported ala4-->val mutation in exon 1 of the SOD1 gene and report that this mutation is both the most commonly detected of all SOD1 mutations and among the most clinically severe. By comparison with our...
