GALC deficiency results in progressive intracellular accumulation of psychosine, which is believed to be the main cause for the demyelinating neurodegeneration in KD pathology. Umbilical cord blood transplantation slows disease progression when performed presymptomatically but carries a significant risk of morbidity and mortality. Accurate presymptomatic diagnosis is therefore critical to facilitate the efficacy of existing transplant approaches and to avoid unnecessary treatment of children who will not develop KD. Unfortunately, current diagnostic criteria, including GALC activity, genetic analysis, and psychosine measurement, are insufficient for secure presymptomatic diagnosis. This study performs a global metabolomic analysis to identify pathogenetic metabolic pathways and novel biomarkers implicated in the authentic mouse model of KD known as\n                    <jats:italic>twitcher<\/jats:italic>\n                    . At a time point before onset of signs of disease, twitcher hindbrains had metabolic profiles similar to WT, with the exception of a decrease in metabolites related to glucose energy metabolism. Many metabolic pathways were altered after early signs of disease in the twitcher, including decreased phospholipid turnover, restricted mitochondrial metabolism of branched\u2010chain amino acids, increased inflammation, and changes in neurotransmitter metabolism and osmolytes. Hypoxanthine, a purine derivative, is increased before signs of disease appear, suggesting its potential as a biomarker for early diagnosis of KD. Additionally, given the early changes in glucose metabolism in the pathogenesis of KD, diagnostic modalities that report metabolic function, such as positron emission tomography, may be useful in KD. \u00a9 2016 Wiley Periodicals, Inc.\n                  <\/jats:p>","DOI":"10.1002\/jnr.23789","type":"journal-article","created":{"date-parts":[[2016,9,17]],"date-time":"2016-09-17T07:22:31Z","timestamp":1474096951000},"page":"1094-1107","source":"Crossref","is-referenced-by-count":14,"title":["Metabolic profiling reveals biochemical pathways and potential biomarkers associated with the pathogenesis of\n                    <scp>K<\/scp>\n                    rabbe disease"],"prefix":"10.1002","volume":"94","author":[{"given":"Nadav I.","family":"Weinstock","sequence":"first","affiliation":[{"name":"Hunter James Kelly Research Institute, Jacobs School of Medicine and Biomedical Sciences State University of New York at Buffalo Buffalo New York"},{"name":"Department of Biochemistry, Jacobs School of Medicine and Biomedical Sciences State University of New York at Buffalo Buffalo New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lawrence","family":"Wrabetz","sequence":"additional","affiliation":[{"name":"Hunter James Kelly Research Institute, Jacobs School of Medicine and Biomedical Sciences State University of New York at Buffalo Buffalo New York"},{"name":"Department of Biochemistry, Jacobs School of Medicine and Biomedical Sciences State University of New York at Buffalo Buffalo New York"},{"name":"Department of Neurology, Jacobs School of Medicine and Biomedical Sciences State University of New York at Buffalo Buffalo New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
