Reduced DNA repair capacity may play a role in amyotrophic lateral sclerosis (ALS) etiology. We examined the association between ALS risk and single nucleotide polymorphisms (SNPs) in the gene x-ray repair complementing defective repair in Chinese hamster cells 1 (XRCC1) utilizing data from a case-control study and 2 genome-wide association studies (the study of Irish Amyotrophic Lateral Sclerosis and the National Institute of Neurological Disorders and Stroke (NINDS) genome-wide study in Amyotrophic Lateral Sclerosis and Neurologically Normal Controls). Our results did not show any differences in the frequency of XRCC1 gene polymorphisms between ALS patients and controls free of any neurological disease.
