Glucose transporter 1 (Glut1), located at the blood–brain barrier, guarantees the facilitated transport of glucose into the brain.[1] Glut1 is coded by SLC2A1 gene, which locates on chromosome 1p34.2 and contains 10 exons.[2] The first disease concerned Glut1 was described by De Vivo et al[3] as Glut1 deficiency syndrome (Glut1-DS). This evidence concerns the gene SLC2A1 and Dravet syndrome.
