What is the official name of the SLC2A1 gene?
The official name of this gene is “solute carrier family 2 (facilitated glucose transporter), member 1.”
SLC2A1 is the gene's official symbol. The SLC2A1 gene is also known by other names, listed below.

What is the normal function of the SLC2A1 gene?
The SLC2A1 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.
In the brain, the GLUT1 protein is involved in moving glucose, which is the brain's main energy source, across the blood-brain barrier. The blood-brain barrier acts as a boundary between tiny blood vessels (capillaries) and the surrounding brain tissue; it protects the brain's delicate nerve tissue by preventing many other types of molecules from entering the brain. The GLUT1 protein also moves glucose between cells in the brain called glia, which protect and maintain nerve cells (neurons).
Does the SLC2A1 gene share characteristics with other genes?
The SLC2A1 gene belongs to a family of genes called SLC (solute carriers).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
