BACKGROUND Mutations in the spastin gene are the commonest cause of hereditary spastic paraparesis (HSP), accounting for up to 40% of autosomal dominant cases. The phenotype associated with HSP due to mutation in the spastin gene (SPG4) tends to be pure HSP. OBJECTIVE To characterize in more detail the genetic and phenotypic characteristics of SPG4 by(More)
Mutations in the transactive response DNA binding protein-43 (TARDBP/TDP-43) gene, which regulates transcription and splicing, causes a familial form of amyotrophic lateral sclerosis (ALS). Here, we characterize and report the first tardbp mutation in zebrafish, which introduces a premature stop codon (Y220X), eliminating expression of the Tardbp protein.(More)
BACKGROUND Lithium has neuroprotective effects in cell and animal models of amyotrophic lateral sclerosis (ALS), and a small pilot study in patients with ALS showed a significant effect of lithium on survival. We aimed to assess whether lithium improves survival in patients with ALS. METHODS The lithium carbonate in amyotrophic lateral sclerosis (LiCALS)(More)
