BACKGROUND The population rate of familial amyotrophic lateral sclerosis (FALS) is frequently reported as 10%. However, a systematic review and meta-analysis of the true population based frequency of FALS has never been performed. METHOD A Medline literature review identified all original articles reporting a rate of FALS. Studies were grouped according to the type of data presented and exami...
The discovery of mutations in the gene for Cu/Zn superoxide dismutase (SOD) in some cases of familial amyotrophic lateral sclerosis (FALS) provides a rationale for enzyme replacement therapy. The inability of SOD to cross the blood-brain barrier motivated this study of the safety, tolerability and pharmacokinetics of bovine SOD (bSOD) administered into the CSF of rhesus monkeys and one late-sta...
Amyotrophic lateral sclerosis (ALS) is a late-onset fatal neurodegenerative disease affecting motor neurons with an incidence of about 1/100,000. Most ALS cases are sporadic, but 5-10% of the cases are familial ALS. Both sporadic and familial ALS (FALS) are associated with degeneration of cortical and spinal motor neurons. The etiology of ALS remains unknown. However, mutations of superoxide di...
A large hexanucleotide (GGGGCC) repeat expansion in the first intron of C9ORF72, a gene located on chromosome 9p21, has been recently reported to be responsible for ~40% of familial amyotrophic lateral sclerosis cases of European ancestry. The aim of the current article was to describe the phenotype of amyotrophic lateral sclerosis cases carrying the expansion by providing a detailed clinical d...
Approximately 10% of cases of amyotrophic lateral sclerosis (ALS), a progressive and fatal degeneration that targets motor neurons (MNs), are inherited, and approximately 20% of these cases of familial ALS (FALS) are caused by mutations of copper/zinc superoxide dismutase type 1. Glutamate excitotoxicity has been implicated as a mechanism of MN death in both ALS and FALS. In this study, we test...
OBJECTIVE Amyotrophic lateral sclerosis (ALS) is a progressive paralytic disorder caused by degeneration of motor neurons. Mutations in the FUS gene were identified in patients with familial ALS (FALS) and patients with sporadic ALS (SALS) from a variety of genetic backgrounds. This work further explores the spectrum of FUS mutations in patients with FALS and patients with FALS with features of...
background: amyotrophic lateral sclerosis (als) is the most common motor neuron disorder in european populations. als can be sporadic als (sals) or familial als (fals). among 20 known als genes, mutations in c9orf72 and superoxide dismutase 1 (sod1) are the most common genetic causes of the disease. whereas c9orf72 mutations are more common in western populations, the contribution of sod1 to al...
Knowledge about the nature of pathomolecular alterations preceding onset of symptoms in amyotrophic lateral sclerosis is largely lacking. It could not only pave the way for the discovery of valuable therapeutic targets but might also govern future concepts of pre-manifest disease modifying treatments. MicroRNAs are central regulators of transcriptome plasticity and participate in pathogenic cas...
Abundant evidence indicates that mitochondrial dysfunction and Ca(2+) dysregulation contribute to the muscle denervation and motor neuron death that occur in mouse models of familial amyotrophic lateral sclerosis (fALS). This perspective considers measurements of mitochondrial function and Ca(2+) handling made in both motor neuron somata and motor nerve terminals of SOD1-G93A mice at different ...
Mutations in the optineurin (OPTN) gene cause amyotrophic lateral sclerosis (ALS). We previously reported three types of OPTN mutation in Japanese ALS subjects. Here, to identify the OPTN mutations in individuals of different ethnicity, we screened 563 sporadic ALS (SALS) subjects and 124 familial ALS (FALS) subjects who were mainly Caucasian. We found a c.964T>C synonymous variation in exon 8....
