What is the official name of the SLC12A3 gene?
The official name of this gene is “solute carrier family 12 (sodium/chloride transporter), member 3.”
SLC12A3 is the gene's official symbol. The SLC12A3 gene is also known by other names, listed below.

What is the normal function of the SLC12A3 gene?
The SLC12A3 gene provides instructions for making a protein known as NCC. This protein is a sodium chloride co-transporter, which means that it moves charged atoms (ions) of sodium (Na+) and chlorine (Cl-) across cell membranes.
The NCC protein is essential for normal kidney function. It is part of the mechanism by which kidneys reabsorb salt (sodium chloride or NaCl) from the urine back into the bloodstream. The retention of salt affects the body's fluid levels and helps maintain blood pressure.
Does the SLC12A3 gene share characteristics with other genes?
The SLC12A3 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.
