ABSTRACT
Citrin deficiency is an autosomal recessive disorder caused by mutation of the SLC25A13 gene, and is one of the most important causes of infant cholestasis in China. The metabolic mechanism of CD is complex, involving the urea cycle, the malate aspartate cycle, the citrate malate cycle, fatty acid metabolism, carbohydrate motabolism and other metabolic pathways. Metabolomics has some applications in CD by analyzing metabolite alterations. This article provides a review for research progress of metabolomics in CD.
ABSTRACT
Inborn Errors of Metabolism (IEM) are diseases caused by genetic defects in the biosynthesis of certain enzymes, receptors, carriers and membrane pumps composed of peptides and/or proteins necessary to maintain normal metabolism of the body, namely, mutations in the genes encoding such peptides (proteins). Through metabolomic analysis of sugars, amino acids, organic acids, fatty acids, carnitine and other substances in blood or urine, as well as cellular enzymology, molecular biology and proteomics analysis. We can identify and quantify abnormal biomarks, determine biomarkers as diagnostic and therapeutic monitoring tools. At the same time, through proteomic research. We can provide scientific basis for the pathogenesis of hereditary metabolic diseases.
