Identification of a minimal region of loss on the short arm of chromosome 1 in Wilms tumor
Bibliographic record
Abstract
We have analyzed the short arm of chromosome 1 using loss of heterozygosity (LOH) analysis in Wilms tumors (WT) to identify a minimal region of loss. 1909 WT, 22 malignant rhabdoid tumors of the kidney and 90 clear cell carcinomas of the kidney (CCSK) were subjected to LOH analysis using five markers flanked by D1S243 and D1S244. 225 WT and 4 CCSK displayed LOH for this region. A group of 16 cases which had lost heterozygosity for at least one locus but also retained heterozygosity for at least one locus within this region were more finely analyzed using a panel of 24 microsatellite markers. A minimum region of loss located between D1S2694 and D1S244 spanning an area of 3.23 Mb was found in 15/16 of these tumors. No evidence for a second locus within this region was identified. This region of loss overlaps that found in neuroblastoma and harbors candidate genes highly expressed in fetal kidney i.e., LZIC, ICAT, and DNB5. Denaturing HPLC and quantitative RT-PCR analysis of these three genes, however, revealed no aberrations in WT samples retaining heterozygosity (8 cases) or displaying LOH 1p (8 cases). Further studies are required to identify the presumed tumor suppressor gene located within this region of 1p.

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.
