Identification of a novel fusion gene involving <i>RUNX1</i> and the antisense strand of <i>SV2B</i> in a <i>BCR‐ABL1</i>‐positive acute leukemia
Bibliographic record
Abstract
RUNX1, a key regulator of hematopoiesis, is frequently mutated or implicated in chromosomal translocations in acute leukemia. About half of RUNX1 translocations remain uncharacterized at the molecular level. We describe here one such event, a t(15;21)(q26.1;q22) translocation identified in an adult patient diagnosed with a t(9;22)(q34;q11.2)-positive acute leukemia. This previously unreported rearrangement yields a fusion of RUNX1 with the antisense strand of the SV2B gene, a new translocation partner of RUNX1, resulting in the expression of out-of-frame mRNA chimeric transcripts and the production of putative truncated RUNX1 isoforms. The t(15;21) translocation also dissociates the P1 promoter of RUNX1 from its open reading frame, reducing RUNX1 expression levels in the patient's leukemic cells. Our data suggest that RUNX1 haploinsufficiency collaborates with the BCR-ABL1 oncogene in this leukemia. The description of this atypical gene fusion is an important addition to the characterization of the pathogenomic mechanisms leading to RUNX1 structural and functional alterations. Furthermore, our data strongly suggests that inadequate dosage of this gene plays an essential role in leukemogenesis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
