LaboratoryCreatine and guanidinoacetate panel - Serum or Plasma
Definition
Measurements of guanidinoacetate (GAA) and creatine (Cr) in serum or plasma are performed for biochemical diagnosis of Guanidinoacetate methyltransferase (GAMT) deficiency, an inherited metabolic disorder of creatine metabolism that is characterized by mental retardation, developmental delay or regression, mental retardation, expressive and cognitive speech delay, and intractable seizures and movement disturbances.[OMIM: 612736] [PMID: 15234334]
