What is the official name of the GSS gene?
The official name of this gene is “glutathione synthetase.”
GSS is the gene's official symbol. The GSS gene is also known by other names, listed below.

What is the normal function of the GSS gene?
The GSS gene provides instructions for making an enzyme called glutathione synthetase. Glutathione synthetase participates in a process called the gamma-glutamyl cycle. The gamma-glutamyl cycle is a sequence of chemical reactions that takes place in most of the body's cells. These reactions are necessary for the production of glutathione, a small molecule made of three protein building blocks (amino acids). Glutathione protects cells from damage caused by unstable oxygen-containing molecules, which are byproducts of energy production. Glutathione is called an antioxidant because of its role in protecting cells from the damaging effects of these unstable molecules. Glutathione also helps process medications and cancer-causing compounds (carcinogens), and helps build DNA, proteins, and other important cellular components.
