What is the official name of the SLC19A3 gene?
The official name of this gene is “solute carrier family 19 (thiamine transporter), member 3.”
SLC19A3 is the gene's official symbol. The SLC19A3 gene is also known by other names, listed below.

What is the normal function of the SLC19A3 gene?
The SLC19A3 gene provides instructions for making a protein called a thiamine transporter, which moves a vitamin called thiamine into cells. Thiamine, also known as vitamin B1, is obtained from the diet. It is involved in many cellular processes, and is necessary for proper functioning of the nervous system. Molecules made from thiamine are important in the breakdown of sugars and protein building blocks (amino acids). Thiamine is also involved in the production of certain chemicals that relay signals in the nervous system (neurotransmitters).
Does the SLC19A3 gene share characteristics with other genes?
The SLC19A3 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.
