Some of the misfolded-SOD1 antibodies in Table 1 (in particular, the ones reported from one research group: SEDI, USOD, AJ10, B8H10, 4A1, and A5E5) were found to immunostain spinal motorneurons in SOD1-ALS but not in non-SOD1 ALS, which might simply mean that misfolded conformations of wild-type SOD1 in non-SOD1 ALS are not the same with those of mutant SOD1 in SOD1-ALS. This evidence concerns the gene SOD1 and amyotrophic lateral sclerosis.
