A previous study [58] looking at how mutations in IDH2 and TET2 cells modulates tumorigenesis in angioimmunoblastic T cell lymphoma (AITL) also found a negative correlation between CpG hypermethylation in a differentially methylated region (DMR) of B3GNT3 and its corresponding expression levels. The gene discussed is B3GNT3; the disease is angioimmunoblastic T-cell lymphoma.
