Abstract

Early T-cell precursor acute lymphoblastic leukaemia (ETP ALL) is an aggressive malignancy of unknown genetic basis. We performed whole-genome sequencing of 12 ETP ALL cases and assessed the frequency of the identified somatic mutations in 94 T-cell acute lymphoblastic leukaemia cases. ETP ALL was characterized by activating mutations in genes regulating cytokine receptor and RAS signalling (67% of cases; NRAS, KRAS, FLT3, IL7R, JAK3, JAK1, SH2B3 and BRAF), inactivating lesions disrupting haematopoietic development (58%; GATA3, ETV6, RUNX1, IKZF1 and EP300) and histone-modifying genes (48%; EZH2, EED, SUZ12, SETD2 and EP300). We also identified new targets of recurrent mutation including DNM2, ECT2L and RELN. The mutational spectrum is similar to myeloid tumours, and moreover, the global transcriptional profile of ETP ALL was similar to that of normal and myeloid leukaemia haematopoietic stem cells. These findings suggest that addition of myeloid-directed therapies might improve the poor outcome of ETP ALL. This work shows that treatments used for acute myeloid leukaemia and targeted therapies could be used for early T-cell precursor acute lymphoblastic leukaemia. The early T-cell precursor (ETP) subtype of childhood acute lymphoblastic leukaemia (ALL) has a poor prognosis when treated with standard chemotherapy. Whole genome sequencing is used here to gain insights into the genetic basis of the condition. The results reveal a high frequency of activating mutations in genes regulating cytokine receptor and Ras signalling, lesions that disrupt haemopoiesis (many of which arise from chromosomal rearrangements that generate novel chimeric in-frame fusion genes), and inactivating mutations in histone modifying genes. This mutation pattern resembles that of myeloid malignancies, suggesting that myeloid-directed therapies such as high-dose cytarabine, or targeted therapies that inhibit cytokine receptor and JAK signalling, might be effective in ETP ALL.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
