Imaging is normal in the majority. Here we describe a 5-month-old boy who presented with motor delay, myoclonic jerks and tonic-clonic seizures. His MRI brain scan revealed confluent symmetrical T2 hyperintense signal abnormality in both anterior frontal lobes and delayed myelination. Neurometabolic screen revealed low CSF glucose and lactate levels. A pathogenic de novo heterozygous mutation in SLC2A1 (c.275+1G > A) confirmed the diagnosis of GLUT1 deficiency. Ketogenic diet resulted in a dramatic termination of his seizures at 72 h. At 15 months, he continued to be seizure free with marked developmental catch up. Repeat imaging revealed a significant resolution of the previously seen changes. This case suggests that GLUT1 deficiency should be considered in the differential diagnosis of infants with suspected genetic leukoencephalopathies with important treatment implications. date: 2018-11 date_type: published publisher: ELSEVIER SCI LTD official_url: https://doi.org/10.1016/j.ejpn.2018.02.002 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1698021 doi: 10.1016/j.ejpn.2018.02.002 lyricists_name: Hacohen, Yael lyricists_id: YHACO24 actors_name: Allington-Smith, Dominic actors_id: DAALL44 actors_role: owner full_text_status: public publication: European Journal of Paediatric Neurology volume: 22 number: 6 pagerange: 1161-1164 pages: 4 citation: Ismayilova, N; Hacohen, Y; MacKinnon, AD; Elmslie, F; Clarke, A; (2018) GLUT-1 deficiency presenting with seizures and reversible leukoencephalopathy on MRI imaging.
