What is the normal function of the DUOX2 gene?
The DUOX2 gene provides instructions for making an enzyme called dual oxidase 2. This enzyme is found in the thyroid gland, which is a butterfly-shaped tissue in the lower neck. The enzyme is also found in salivary glands, the digestive tract, and airways in the throat and lungs. Dual oxidase 2 helps generate a chemical called hydrogen peroxide. In the thyroid, hydrogen peroxide is required for one of the final steps in the production of thyroid hormones. Thyroid hormones play an important role in regulating growth, brain development, and the rate of chemical reactions in the body (metabolism).
Does the DUOX2 gene share characteristics with other genes?
The DUOX2 gene belongs to a family of genes called EF-hand domain containing (EF-hand domain containing).
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.
