TET dioxygenases are known to have tumour suppressor activity. Here, An et al. show that Tet2/Tet3 double conditional mutant mice develop aggressive myeloid leukaemia, and suggest that rather than increased DNA methylation, aberrant gene expression and defects in DNA damage response and repair are the major drivers of myeloid leukaemogenesis upon TET loss-of-function.
