N-(9-β-D-Ribofuranosyl-9H-purin-6-yl)-L-aspartic Acid; 6-(1,2-Dicarboxyethylamino)|-9-β-D-ribofuranosylpurine; (S)-N-(1,2-Dicarboxyethyl)adenosine; Succinoadenosine

Succinyladenosine (S-Ado) is a biochemical marker of adenylosuccinase deficiency - the genetic defect of purine de novo synthesis.  S-Ado has been previously reported as normally undetectable in cerebrospinal fluid (CSF) of children not suffering from this defect.
