413 Possible Causes for L leucinal

  • HMG-CoA Lyase Deficiency

    Abstract 3-Hydroxy-3-methylglutaryl-CoA lyase (HL) deficiency is a rare autosomal recessive genetic disorder that affects ketogenesis and l-leucine catabolism, which generally[ncbi.nlm.nih.gov] […] gene cause 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (HMGCLD), a rare autosomal recessive inborn error of metabolism characterized by disruption of ketogenesis and L-leucine[en.wikipedia.org] Condition Description 3-Hydroxy-3-methylglutaryl-CoA lyase (HMG) deficiency is an autosomal recessive disorder that affects ketogenesis and L-leucine catabolism[1].[egl-eurofins.com]

  • Maple Syrup Urine Disease

    For all three patients, plasma leucine levels decreased dramatically from 2186, 3818 and 2536 mumol/L to 1131, 1275 and 488 mumol/L, respectively.[ncbi.nlm.nih.gov] In vivo catabolism was investigated by measuring the metabolic L-alloisoleucine clearance and whole-body leucine oxidation in the postabsorptive state.[ncbi.nlm.nih.gov] None of the five patients met criteria to be considered presumptive positive for MSUD (leucine 200micromol/L and a ratio of leucine/alanine or 1.5).[ncbi.nlm.nih.gov]

  • Diamond-Blackfan Anemia

    Furthermore, we showed that loss of Rps19 or Rps14 activates the mTOR pathway, and this is accentuated by L-leucine in both Rps19 and Rps14 morphants.[ncbi.nlm.nih.gov] Several preclinical studies with DBA lymphocytes exposed to various L-leucine doses, have demonstrated that protein synthesis can be increased by using high doses L-leucine[clinicaltrials.gov] L-Leucine treatment alleviated the defects of protein production in erythroid cells and partially rescued the anemic phenotype in both rps19 and rpl11 mutants.[ncbi.nlm.nih.gov]

  • Isovaleric Acidemia

    Isovaleryl CoA dehydrogenase, which is located in the mitochondria, is important for metabolism of L-leucine.[thefreelibrary.com] Total conjugate excretion was highest after a leucine load during combined glycine and L-carnitine therapy.[ncbi.nlm.nih.gov] Administration of equimolar amounts of glycine or L-carnitine separately with leucine demonstrated that isovaleryl-coenzyme A is removed by supplemental L-carnitine in the[ncbi.nlm.nih.gov]

  • Cyanogenic Glycoside

    , Lleucine, L‐phenylalanine, or L‐tyrosine, and cyclopentenyl‐glycine (a nonprotein amino acid) [ 2 , 10 ].[intechopen.com] Despite great deal of structural diversity in cyanogenic glycosides, almost all of them are believed to be derived from only six different amino acids L‐valine, L‐isoleucine[intechopen.com]

  • Leucine-induced Hypoglycemia

    SPONTANEOUS hypoglycemia in infancy may, on rare occasions, be precipitated by the ingestion of casein, L-leucine or isovaleric acid, an intermediary metabolite of leucine[nejm.org] The idea and the logic in choosing L-Leucine for testing its potential action against occurrence of seizures lie in the fact that L-Leucine is a ketogenic amino acid; its[icaas-org.com] Katz LE, Stanley CA Title Familial leucine-sensitive hypoglycemia of infancy due to a dominant mutation of the beta-cell sulfonylurea receptor.[genome.jp]

  • Hyperammonemia

  • Intermittent Maple Syrup Urine Disease

    Whole-body L-leucine oxidation was assessed in patients with maple syrup urine disease of different severity using oral L-[1-(13)C]leucine bolus tests (38 micromol/kg body[wikigenes.org] FIGURE 3 Plasma L-leucine concentrations and interorgan relationships of BCAA and BCKA degradation of a classic MSUD patient before and after OLT.

    Safe plasma leucine levels also seemed to be 400–500 μmol/L.[jn.nutrition.org] […] and valine levels may drop rapidly and very low levels (isoleucine 100 umol/L and valine 200 umol/L) will keep the leucine level from dropping by limiting protein synthesis[newenglandconsortium.org] 275 to 393 μmol/L.[clinchem.aaccjnls.org]
