Description : Sarcosinemia is characterized by an increased concentration of sarcosine in plasma
and an increased excretion of sarcosine in urine. Sarcosine (N-methylglycine) is enzymatically
formed from dimethylglycine by dimethylglycine dehydrogenase (EC 1.5.99.2) and converted
to glycine by sarcosine dehydrogenase (SARDH; 604455; EC 1.5.99.1). Some reports have
associated sarcosinemia with mental retardation and neurologic problems, but the disorder
is most likely benign and unrelated to significant clinical problems (summary by Scott,
2001).;
