Several mutations in sod- have been identified in patients but how do these mutations result in toxic proteins, and what can knowing the mutation-type tell us about the behaviour.
From control (two cases; neurologically normal), sporadic als (three cases), and autosomal dominant fals (three cases, one sod- a4v mutation and two without linkage to sod-1). In asymptomatic sod- carriers cortical excitability was normal in two pre-symptomatic sod- mutation carriers sici was markedly reduced (sici patient, -32%; patients, -.
