- Background A known cause of ALS are mutations in the SOD1 gene. There is also evidence that SOD1 may be involved in cases lacking mutations in the gene. A 50 bp deletion located 1684 bp upstream of the start codon of SOD1 has been suggested to reduce transcription of SOD1, affect enzymatic activity and to be associated with later disease onset in ALS patients. The findings have been challenged by a study of Italian ALS patients, and here we examined the 50 bp deletion in Swedish ALS patients and controls. Methods Blood samples from 543 Swedish ALS patients and 356 Swedish controls were analysed for the 50 bp deletion and for SOD1 enzymic activity. The results were related to the disease phenotype of the patients.Results The frequency of the 50 bp deletion was the same in the patient and control cohorts, and both were found to be in Hardy-Weinberg equilibrium regarding the deletion. In relation to the different genotypes, no differences were detected in SOD1 enzymic activity, duration of disease, age of onset or site of onset.Conclusions When interpreting the present results together with previous results from other populations, we find it unlikely that the 50 bp deletion region has any regulatory function for the SOD1 gene, nor any effects on the phenotype of ALS.
