The Ten-Eleven Translocation-2 (TET2) gene, located on chromosome 4q24, has been implicated in hematological malignancies. The TET2 gene shows mutations in variable myeloid malignancies with the involvement of 15% of myeloproliferative neoplasms (MPNs). The inactivation of the TET2 gene in both mice and humans has shown a high degree of deregulation of the hematopoiesis process leading to hematological malignancies. Polycythemia vera (PV), an MPN characterized by increased red blood cell mass, has been associated with the TET2 gene. Furthermore, TET2 genes have been found to facilitate Janus kinase-2 and signal transducer activator of transcription 5, as well as modulate the epigenetic composition of genomic DNA. However, little is known about the role of TET2 mutations in patients with PV. Several studies have been conducted to further assess the significant role of TET2 gene function in various disease processes and prognoses to enhance the management and care of these patients.
