Abstract
Concurrent perturbations in different driver genes have been reported primarily in lymphoma. In acute myeloid leukemia (AML), cases with concurrent alterations in 2 driver genes are infrequently reported. In contrast to pathogenetic pathways in lymphoma with concurrently perturbed genes, the initial gene alteration in AML arrests maturation and the alteration in the second gene promote self-renewal of the blasts. Here, we report a unique case of infantile leukemia in which chromothripsis in chromosome 8 completely altered the G-band structure and resulted in concurrent changes in MOZ/NCOA2, FGFR1, RUNX1T1, and RUNX1. These multiple-hit abnormalities in AML have not been reported previously.
