Genetic variation in the promoter and 5′ UTR of the copper transporter, <i>ATP7B</i>, in patients with Wilson disease
Bibliographic record
Abstract
ATP7B is a copper-transporting P-type ATPase defective in the copper transport disorder, Wilson disease (WND). We have sequenced the 5' UTR and promoter region of ATP7B in 37 unrelated WND patients in whom partial sequencing of the coding region and intron/exon boundaries of the gene had failed to identify one or both disease-causing mutations. Three patients were found to be heterozygous for a 15 bp deletion between nucleotides -424 and -441. This deletion had been previously identified as the most common mutation in Sardinian WND patients. Two novel single-nucleotide changes were also identified within the 5' UTR and promoter of ATP7B; however, these were found at a similar frequency in control chromosomes and are apparently normal variants. These results suggest that mutations in regulatory elements of ATP7B are uncommon in patients of European ancestry, except in Sardinia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
