TET2 overexpression in NHL is not well explored when compared to well-documented trends of downregulation in TET2 within various haematological malignancies (Chiba, 2017); however, previous studies have established this same trend of TET2 over-expression in CLL as observed in our study (Hernández-Sánchez et al., 2014). This evidence concerns the gene TET2 and non-Hodgkin lymphoma.
