Localization of a mutant SOD1 protein in E40K-heterozygous dogs: Implications for non-cell-autonomous pathogenesis of degenerative myelopathy

Yui Kobatake, Hiroki Sakai, Toshihiro Tsukui, Osamu Yamato, more

Journal of the Neurological Sciences > 2017 > 372 > C > 369-378

Canine degenerative myelopathy (DM) is a fatal neurodegenerative disorder. Dogs with typical clinical signs carry homozygous mutations in the superoxide dismutase 1 (SOD1) gene; therefore, DM is regarded as a naturally-occurring model of amyotrophic lateral sclerosis (ALS). Despite the presence of a toxic mutant protein, E40K-SOD1 heterozygotes rarely develop clinical signs. Therefore, E40K-heterozygotes...
