Abstract

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is caused by impaired glucose transport across the blood-brain barrier (BBB) and characterized by infantile seizures, developmental delay, acquired microcephaly, spasticity, ataxia, and a low cerebrospinal glucose concentration (hypoglycorrhachia). A diagnosis of GLUT1-DS is biochemically established in neurologically impaired patients with hypoglycorrhachia in the normoglycemia. GLUT1-DS can be confirmed by mutation analysis of the solute carrier family 2 (facilitated glucose transporter), member 1 (SLC2A1) gene or reduced 3-O-methyl-D-glucose uptake into erythrocytes. The patient was a 12-year-old boy born at term. He had experienced seizures from 4 months of age. Electroencephalography (EEG) did not show epileptiform activity. Brain magnetic resonance imaging (MRI) revealed mild diffuse cortical atrophy and ventricular dilatation. Furthermore, he showed developmental delay, mental retardation, and ataxia, which all became more apparent with age progression. For 7 years, he had experienced paroxysmal episodes of atonic behavioral changes that were aggravated before meals or when he became tired. When he was 12 years old, cerebrospinal fluid (CSF) analysis revealed a low glucose concentration in the normal serum glucose and lactate levels. Under the impression of GLUT1-DS, mutation analysis of the SLC2A1 gene by direct sequencing was performed using white blood cells, and c.680-2delA of intron 5 was found. We describe a GLUT1-DS patient with a typical natural history of GLUT1-DS through a long term follow-up visits, with a novel splice site mutation (SLC2A1: c.6802delA).
