What is the official name of the SLC12A1 gene?
The official name of this gene is “solute carrier family 12 (sodium/potassium/chloride transporter), member 1.”
SLC12A1 is the gene's official symbol. The SLC12A1 gene is also known by other names, listed below.

What is the normal function of the SLC12A1 gene?
The SLC12A1 gene provides instructions for making a protein known as NKCC2. This protein is a Na+/K+/2Cl- cotransporter, which means that it moves charged atoms (ions) of sodium (Na+), potassium (K+), and chlorine (Cl-) into cells.
The NKCC2 protein is essential for normal kidney function. The NKCC2 protein works with other transport proteins to regulate the movement of ions into and out of kidney cells. Together, these proteins provide 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 SLC12A1 gene share characteristics with other genes?
The SLC12A1 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.
