Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurological disease. Mutations of the Cu/Zn superoxide dismutase gene (SOD1) are responsible for 20% of autosomal dominant familial ALS (FALS). Results: We examined the clinical features of the first Italian FALS with the Leu144Phe SOD1 mutation. Seven affected members were identified in a six-generation pedigree. A slowly progressive course (20.4±14.6 years) was observed in five patients. One patient died of cardiac failure two years after the onset of the disease. The propositus is still alive. Neurological manifestations began in the legs in all patients, while bulbar signs were absent or appeared late in the course of the disease. Discussion: There is evidence of a correlation between this mutation and a slowly progressive phenotype of ALS. Moreover this rare mutation might derive from a common ancestor.
