Abstract
A new patient aVected by Guanidinoacetate methyltransferase (GAMT) deWciency was reported. This 13-year-old girl presented with mental retardation, as main symptom, associated with a typical pattern of biochemical and neurochemical (brain magnetic resonance spectroscopy) alterations. Molecular study detected a L197P transition on exon 6 of the GAMT gene. Since this mutation leaves the isoform B of the GAMT enzyme unaVected, the occurrence of biochemical alterations and disease in this subject testiWes against the possibility that isoform b had GAMT activity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
