What is the official name of the TET2 gene?
The official name of this gene is “tet methylcytosine dioxygenase 2.”
TET2 is the gene's official symbol. The TET2 gene is also known by other names, listed below.

What is the normal function of the TET2 gene?
The TET2 gene provides instructions for making a protein whose function is unknown. Based on the function of similar proteins, researchers believe the TET2 protein is involved in regulating the process of transcription, which is the first step in protein production. Although this protein is found throughout the body, it may play a particularly important role in the production of blood cells from hematopoietic stem cells. These stem cells are located within the bone marrow and have the potential to develop into red blood cells, white blood cells, and platelets. The TET2 protein appears to act as a tumor suppressor, which is a protein that prevents cells from growing and dividing in an uncontrolled way.
How are changes in the TET2 gene related to health conditions?
Where is the TET2 gene located?
Cytogenetic Location: 4q24
