Compared to several other ALS microarrays (Brockington et al. 2010; Chen et al. 2010; Cox et al. 2010; D’arrigo et al. 2010; Ferraiuolo et al. 2007; Ferraiuolo et al. 2011; Gonzalez De Aguilar et al. 2008; Jiang et al. 2005; Kirby et al. 2005; Kudo et al. 2010; Vargas et al. 2008; Yoshihara et al. 2002), we identified five genes from our ≥2-fold change list that have orthologs in SOD1 transgenic mice and human patients with sporadic ALS (Table 1). This evidence concerns the gene SOD1 and amyotrophic lateral sclerosis.
