Summary: Intermediate CAG (polyQ) expansions in the ATXN2 gene are associated with amyotrophic lateral sclerosis (ALS). Expansions of >= 31 repeats increase the risk for ALS and even greater risk for ALS with frontotemporal dementia (FTD).

Summary: This study characterized the prototypical phenotype of patients with amyotrophic lateral sclerosis (ALS) associated with PFN1 mutations and identified clinical indications for testing mutations in this gene. The main clinical findings for familial ALS linked to PFN1 were identified as pedigrees with over five cases, an onset age around 50 years, onset in the lower limbs, and the absence of cognitive impairment. The similarities with other ALS mutations prompt a review of ALS classifications based on both phenotype and genotype.

Summary: Mendelian randomization studies on amyotrophic lateral sclerosis show a causal link between blood lipids and the disease risk, while factors like smoking and immune function require further investigation for confirmation. The use of high methodological standards and replication across different datasets are essential for reliable results in Mendelian randomization studies.

Summary: The study found that PLS and ALS cases occurred in nine families, generally among first-degree relatives. Patients with both diseases exhibited typical disease characteristics, and genetic studies revealed mutations in specific genes in some patients. These results strongly support a phenotypic continuum between PLS and ALS.

Summary: Amyotrophic lateral sclerosis (ALS) is characterized by the progressive loss of motor neurons and biomarkers for ALS are important for disease detection and therapeutic targets. This study conducted a systematic review and meta-analyses of genetic loci associated with ALS using genome-wide association studies (GWASs). Aminopeptidases were identified as possible biomarkers, but the meta-analyses did not show a risk association between the genetic variation rs1060404 in the DPP6 gene and ALS.

Summary: This pilot study did not find a strong pathological role of exosome-derived miRNA in ALS, but identified six biological processes shared across miRNAs in samples with the highest miRNA content. Further investigation is needed to elucidate the role of exosome-derived miRNA in ALS.

Summary: Amyotrophic lateral sclerosis (ALS) is a genetically complex neurodegenerative disease that is associated with immune dysfunction. Neuroinflammation, characterized by abnormal immune cell activation and excessive production of inflammatory cytokines, plays a significant role in the pathophysiology of ALS. This review examines recent evidence on the role of ALS-associated mutant genes in immune dysregulation, with a focus on the cGAS-STING signaling pathway and m6A-mediated immune regulation in neurodegeneration. It also discusses immune cell perturbation in both the central nervous system and peripheral tissues in ALS, as well as advancements in genetic and cell-based therapies for ALS. Understanding the complex relationship between ALS and neuroinflammation is crucial for the development of effective treatments for this debilitating disorder.

Summary: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects motor neurons, leading to muscle weakness, paralysis, and eventual death. Recent research has shown that ALS is not only limited to motor neurons, but also involves systemic metabolic dysfunction. This review examines the metabolic dysfunction in ALS at various levels, including muscle tissue, adipose tissue, liver, pancreas, and the central nervous system. It also discusses the future prospects of metabolic research in ALS and potential treatment options.

Summary: GGC repeat expansions in the 5'UTR of the NOTCH2NLC gene have been found to cause neuronal intranuclear inclusion disease (NIID), but their presence in other neurodegenerative disorders is unclear. In this study, we investigated the presence of a medium-length amplification of NOTCH2NLC in patients with amyotrophic lateral sclerosis (ALS). We identified intermediate GGC repeat expansions in two ALS patients but not in the control group, suggesting their association with ALS in Chinese patients.

Summary: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder characterized by progressive loss of motor neurons (MNs) in the brain and spinal cord. The aggregation and accumulation of ubiquitinated protein inclusions in degenerating MNs are key pathological features of ALS. Recent research has provided insights into the molecular mechanisms underlying protein aggregate accumulation in ALS, which may aid in the development of therapeutic strategies.

Summary: This article reviews the progress in the diagnosis, monitoring, and treatment of amyotrophic lateral sclerosis (ALS). Despite the difficulty in diagnosing and the lack of a cure for ALS, there is evidence to suggest that an optimistic view of ALS management in the coming years is now realistic.

Summary: This study found that serum ADMA level is associated with the progression and prognosis of amyotrophic lateral sclerosis (ALS) and is an independent biomarker for ALS disease progression and prognosis, reflecting the degree of motor neuron degeneration.

Summary: Mutations in the HADHB gene cause Mitochondrial Trifunctional Protein (MTP) deficiency, leading to the inability to metabolize long-chain fatty acids in affected patients. Different clinical manifestations are associated with this deficiency, with the pathophysiology of sensorimotor neuropathy remaining relatively unknown.

Summary: Autosomal Recessive Spastic Ataxia of the Charlevoix Saguenay (ARSACS) is a genetic disease caused by mutation in the SACS gene, resulting in loss of function of the protein sacsin. The SacsJ domain of sacsin plays a key role in regulating the neurofilament (NF) and vimentin intermediate filament (IF) networks in cells.
