Glucose Transporter 1 Deficiency Syndrome (GLUT1-DS; OMIM #606777) is a rare neurometabolic disorder resulting from an autosomal dominant mutation in SLCA1 (solute carrier family 2 member 1), a gene that encodes GLUT-1, the main transporter of glucose across the blood–brain barrier (BBB) and the plasma membrane of astrocytes. This evidence concerns the gene SLC2A1 and Dravet syndrome.
