TET2 loss triggers ssDNA gap accumulation and heightened PARP inhibitor sensitivity

Somatic mutations in the de novo methyltransferase DNMT3A and cytosine demethylase TET2 are common in age-related clonal hematopoiesis and hematopoietic neoplasms. TET2 mutations, unlike DNMT3A mutations, increase sensitivity to PARP inhibitors (PARPi). We find that TET2 loss, bu...
