Two studies recently identified a GGGGCC hexanucleotide repeat expansion in a non-coding region of the chromosome 9 open-reading frame 72 gene (C9ORF72) as the cause of chromosome 9p-linked amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). In a cohort of 231 probands with ALS, we identified the C9ORF72 mutation in 17 familial (27.4%)(More)
Mutations in the fused in sarcoma (FUS) gene have recently been found to cause familial amyotrophic lateral sclerosis (FALS). We screened FUS in a cohort of 200 ALS patients [32 FALS and 168 sporadic ALS (SALS)]. In one FALS proband, we identified a mutation (p.R521C) that was also present in her affected daughter. Their clinical phenotype was remarkably(More)
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a devastating cause of progressive weakness, respiratory failure and death. To date there is no effective therapy to meaningfully extend survival but continuously emerging targets and putative treatments are studied in clinical trials. Canadian epidemiological data on ALS is scarce and the socioeconomic(More)
BACKGROUND Patient registries represent an important method of organizing "real world" patient information for clinical and research purposes. Registries can facilitate clinical trial planning and recruitment and are particularly useful in this regard for uncommon and rare diseases. Neuromuscular diseases (NMDs) are individually rare but in aggregate have a(More)
Neuropathies are associated with several systemic diseases. This article provides a general overview of the clinical presentation and management of the various neuropathies associated with common medical illnesses. The term "neuropathy" is used relatively broadly to encompass pathology from the level of the cell body to the terminal axon. Peripheral nerve(More)
