Creatine, guanidinoacetate & creatinine pattern
Increased guanidinoacetate (GAA) is a marker for the diagnosis of guanidinoacetate methyltransferase (GAMT) deficiency. Almeidaa et al (2004) found the GAA levels to be 4-130 times increased in urine in patients with GAMT deficiency compared to controls.[PMID15234334]
