The Catalase (CAT) gene is associated with the synthesis of catalase, an enzyme found to be associated with the conversion of superoxide (O2-) into oxygen (O2) and hydrogen peroxide (H2O2). It is a heme enzyme and is present in the peroxisome of almost all aerobic cells.
Superoxide is formed in the body as a byproduct of oxygen metabolism and it can result in damage to the cell. Catalase is one of the important antioxidant enzymes in the body. People with the T variant of the gene are shown to be associated with lower catalase activity.

In a study conducted on people with prostate cancer, people with the T variant of the gene were shown to be associated with advanced stages of the disease when compared to people with the C variant of the gene. The rare variant (T) is found to be associated with lower catalase activity which may lead to deficient antioxidant protection against oxidative stress, potentially increasing the risk of disease.
