TP53 mutations are frequent in adult acute lymphoblastic leukemia cases negative for recurrent fusion genes and correlate with poor response to induction therapy

Acute lymphoblastic leukemia (ALL) is a disease of either B-cell (80–85%) or T-cell (20–25%) derivation. Several molecular aberrations (i.e. BCR-ABL1, MLL/AFF1, SIL/TAL1 and E2A/PBX1 ) confer an overall poor outcome.[1][1],[2][2] However, a proportion of patients do not carry known genetic
