What is the official name of the SLC17A5 gene?
The official name of this gene is “solute carrier family 17 (acidic sugar transporter), member 5.”
SLC17A5 is the gene's official symbol. The SLC17A5 gene is also known by other names, listed below.

What is the normal function of the SLC17A5 gene?
The SLC17A5 gene provides instructions for producing a protein called sialin that is located mainly on the membranes of lysosomes, compartments in the cell that digest and recycle materials. Sialin moves a molecule called free sialic acid, which is produced when certain proteins and fats are broken down, out of the lysosomes to other parts of the cell. Free sialic acid means that the sialic acid is not attached (bound) to other molecules.
Researchers believe that sialin may also have other functions in brain cells, in addition to those associated with the lysosomes, but these additional functions are not well understood.
Does the SLC17A5 gene share characteristics with other genes?
The SLC17A5 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.
