Creatine synthesis deficiency

WebCreatine deficiency syndromes, which have only recently been described, represent a group of inborn errors of creatine synthesis (L-arginine-glycine amidinotransferase deficiency and guanidinoacetate methyltransferase deficiency) and transport (creatine transporter deficiency). WebThis enzyme participates in the two-step production (synthesis) of the compound creatine from the protein building blocks (amino acids) glycine, arginine, and methionine. Specifically, arginine:glycine amidinotransferase controls the first step of the process.

WebCreatine deficiency syndromes (CDS) are a novel group of inborn errors of creatine synthesis and transport including autosomal recessive arginine:glycine amidino transferase (AGAT) and guanidinoacetate methyltransferase (GAMT) deficiencies, and the X-linked creatine transporter (SLC6A8) deficiency. WebApr 12, 2024 · In particular, we demonstrate that NH4+ exposure decreases both creatine and its synthesis intermediate, guanidinoacetate, in brain cells, probably through the inhibition of AGAT enzymatic activity. WebCreatine transporter deficiency (CTD) will be missed if only plasma is screened because males with this disorder have normal creatine in plasma; urine is needed to make this diagnosis in males. *Inclusion of urine screening is recommended because CTD can appear normal in plasma screening. bruce fitch office

WebJan 1, 2010 · In patients with arginase deficiency, markedly elevated arginine levels may result in higher concentrations of guanidinoacetate and higher rates of creatine synthesis. This is of concern because it is thought that elevated levels of guanidinoacetate may exert neurotoxic effects. Creatine is a naturally occurring non-protein compound and the primary constituent of phosphocreatine, which is used to regenerate ATP within the cell. 95% of the human body's total creatine and phosphocreatine stores are found in skeletal muscle, while the remainder is distributed in the blood, brain, testes, and other tissues. The typical creatine content of skeletal muscle (as both creatin…
