Brain glucose transport is dependent on glucose transporter 1 (GLUT1), encoded by the solute carrier family 2 member 1 (SLC2A1) gene. Mutations in SLC2A1 cause GLUT1 deficiency which is characterized by a broad spectrum of neurological phenotypes including generalized epilepsy, motor disorders, developmental delay and microcephaly. Recent case reports suggest SLC2A1 mutations can contribute to non-acquired focal epilepsy (NAFE) but interrogation of a large patient cohort has not been reported. We studied 200 patients with NAFE (126 with temporal lobe epilepsy) comprising 104 females and 96 males with a mean age of onset of 18 years. Polymerase chain reaction (PCR) and Sanger sequencing was p..
