Novel SOD1 mutation p.V31A identified with a slowly progressive form of amyotrophic lateral sclerosis.

Abstract excerpt

The SOD1 gene encoding the superoxide dismutase 1 (SOD1) protein is mutated in approximately 15% of familial amyotrophic lateral sclerosis (ALS) and 3% of sporadic ALS. We identified a novel mutation in SOD1 in a man who presented at age 49 with lower limb stiffness, and at age 53, a spastic paraparesia with distal muscular atrophy in the lower limbs and fasciculations in the quadriceps. A diagnosis of ALS was...
