Mapping the cellular origin and early evolution of leukemia in Down syndrome
Bibliographic record
Abstract
Down with leukemia Down syndrome is a congenital disorder caused by the trisomy of chromosome 21, and it is associated with a greatly increased risk of leukemia with origins in fetal development. Infants with Down syndrome are often born with a preleukemic condition, which later resolves in most cases. By using gene-edited human cells implanted into mouse models, Wagenblast et al. recapitulated the development of preleukemia and leukemia in the context of Down syndrome (see the Perspective by Roberts and Vyas). A specific mutation triggered a preleukemic condition in the context of trisomy 21 as expected, but progression to full-blown leukemia required a different genetic path and was not dependent on trisomy 21.

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.
