What is the official name of the SLC19A2 gene?
The official name of this gene is “solute carrier family 19 (thiamine transporter), member 2.”
SLC19A2 is the gene's official symbol. The SLC19A2 gene is also known by other names, listed below.

What is the normal function of the SLC19A2 gene?
The SLC19A2 gene provides instructions for making a protein called thiamine transporter 1. This protein is located on the surface of cells, where it works to bring vitamin B1 (thiamine) into cells. Thiamine helps the body convert carbohydrates into energy, and it is also essential for the functioning of the heart, muscles, and nervous system. This vitamin must be obtained from the diet because the body cannot produce thiamine on its own. Many different foods contain thiamine, including whole grains, pasta, fortified breads and cereals, lean meats, fish, and beans.
Does the SLC19A2 gene share characteristics with other genes?
The SLC19A2 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.
