WebResults: In AML, MDM2 LOH was concomitant with TP53 missense mutations, but not TP53 deletions or truncations (log2 odds ratio > 3, P < 0.001). This association was not present in lymphomas, in which we found MDM2 LOH and TP53 mutations to be mutually exclusive. Webnot self-renewal. We show that p53 inactivation strongly cooperates with oncogenic KrasG12D to induce aggressive AML, while both lesions on their own induce T-cell malignancies with long latency. This synergy is based on a pivotal role of p53 in limiting aberrant self-renewal of myeloid progenitor cells, such that loss of p53 counters the
