Abstract
Wilson disease (WND) is caused by mutations in the ATP7B gene and exhibits substantial allelic heterogeneity. In this study we report the results of molecular analyses of 20 WND families not described previously. When combined with our prior results, the cohort includes 93 index patients from 69 unrelated families. Twenty different mutations accounted for 86% of the WND chromosomes. The most frequent were p.H1069Q (35%), p.R969Q (12%), c.2530delA (7%), p.L936X (7%), p.Q289X (7%), and p.I1148T (3%). We also present here a detailed phenotypic assessment for patients whose molecular result was previously reported. Thirty cases were homozygous for 9 different mutations, 13 of which were homozygous for p.H1069Q, and 7 for p.R969Q. Mutations p.H1069Q and p.R969Q appeared to confer a milder disease as patients showed disease onset at a later age, and were associated with milder severity when found in trans with severe mutations. Predicted nonsense and frameshift mutations were associated with severe phenotypic expression with earlier disease onset and lower ceruloplasmin values. WND can be treated by copper-chelation therapy, particularly if the disease is diagnosed before irreversible tissue damage occurs. Our results on the effect of predicted nonsense and frameshift mutations are especially important for early medical intervention in presymptomatic infants and children with these genotypes.

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 it
