    ### Instruction:
    What are the genetic changes related to GLUT1 deficiency syndrome ?
    ### Response:
    GLUT1 deficiency syndrome is caused by mutations in the SLC2A1 gene. This gene provides instructions for producing a protein called the glucose transporter protein type 1 (GLUT1). The GLUT1 protein is embedded in the outer membrane surrounding cells, where it transports a simple sugar called glucose into cells from the blood or from other cells for use as fuel.
