Myelodysplastic syndromes are characterised by clonal haematopoiesis, with the affected cells often harbouring mutations in the TET2 gene, an important regulator of DNA methylation state. Here authors show that the same mutations are also found in NK cells, perturbing their DNA methylation pattern and cytolytic function.
