However, untargeted metabolomics as first line diagnostics for rare disease is now only gradually making its way into clinical practice. Most retrospective studies show that the majority of inborn metabolic disorder can be detected through untargeted metabolomics. Some diseases will still go undetected, which diagnoses are missed depends on the specific metabolomics method chosen; there is no single all-encompassing platform. Therefore, careful assessments of the opportunities and limitations are currently undertaken in prospective studies, combining untargeted metabolomics in the diagnostics setting with the current gold standard genetic and biochemical diagnostic modalities. These studies show an increased diagnostic yield when implementing untargeted metabolomics. Given the continuing technological advances, defining the optimal timing, place, and order of the various diagnostic modalities will keep on evolving in the foreseen future.</p></div>","PeriodicalId":37400,"journal":{"name":"Current Opinion in Systems Biology","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2452310021001049/pdfft?md5=967143ed4644a1e92c1cb82efc3ba605&pid=1-s2.0-S2452310021001049-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42607685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several genetic studies link these diseases with lysosomal dysfunction; however, a mechanistic understanding of how lysosomal perturbations result in neurodegeneration is unclear. Neuronopathic lysosomal storage disorders represent an attractive model for elucidating such mechanisms as they share several metabolic pathological hallmarks with common neurodegenerative diseases. This review explores how altered lipid metabolism, calcium dyshomeostasis, mitochondrial dysfunction, </span>oxidative stress, and impaired autophagic flux contribute to cellular pathobiology in age-related neurodegeneration and neuronopathic lysosomal storage disorders. It further debates whether general lysosomal dysfunction owing to toxic substrate accumulation or extralysosomal nutrient deprivation drives these downstream processes. With increasing evidence for the latter, future studies should investigate additional lysosomal nutrients that protect against neurodegeneration using emerging subcellular ‘omics’-based technologies with the promise of identifying therapeutic targets for the treatment of neurodegenerative diseases.</p></div>","PeriodicalId":37400,"journal":{"name":"Current Opinion in Systems Biology","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41515878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
