HFE gene mutations in patients with rheumatoid arthritis.
Bibliographic record
Abstract
OBJECTIVE: To investigate the role of C282Y and H63D mutations in HFE gene in susceptibility to rheumatoid arthritis (RA). METHODS: The distribution of C282Y and H63D mutations in patients with RA and in healthy subjects was examined by restriction endonuclease digestion of polymerase chain reaction amplified genomic DNA. RESULTS: The prevalence of C282Y mutation in patients with RA was the same as in healthy controls. In contrast, the distribution of H63D mutation was significantly higher in the total RA patient population and in DRB1 QKRAA/QRRAA epitope positive patients compared to respective groups of controls. Analysis of data showed that (1) both H63D mutation and QKRAA/QRRAA DRB1 epitope are individually associated with RA susceptibility; (2) there is interaction between these 2 factors in development of RA; and (3) both these factors combined have stronger association with RA susceptibility than with these factors individually. CONCLUSION: H63D mutation appears to play a role in pathogenesis of RA. This study is small and must be regarded as preliminary. These data therefore need confirmation from independent studies.

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.
