SKY confirmed the rarity of clonal translocations in p53−/− T cell lymphomas (Deriano et al., 2011), while, more surprisingly, most Rag2−/−p53−/− lymphoma analyzed harbored recurrent translocations involving chromosome 9 (Figure 1B; Table S3). The gene discussed is TP53; the disease is T-cell non-Hodgkin lymphoma.
