Cerebral 1H MR spectroscopy showing elevation of brain guanidinoacetate in argininosuccinate lyase deficiency

Mol Genet Metab. 2006 May;88(1):100-2. doi: 10.1016/j.ymgme.2005.10.013. Epub 2005 Dec 15.

Abstract

MR spectroscopy in a patient with argininosuccinate lyase deficiency revealed elevated cerebral guanidinoacetate signals, indicating that the phenomenon of increased levels of this compound in brain tissue is not limited to creatine deficiencies.
