What have we learned about genetic susceptibility in psoriasis and psoriatic arthritis?
Bibliographic record
Abstract
PURPOSE OF REVIEW: To review recent evidence for genetic susceptibility in psoriasis and psoriatic arthritis. RECENT FINDINGS: Psoriasis and psoriatic arthritis (PsA) have substantive genetic determinants as indicated by their high family aggregation. Psoriasis and PsA share several susceptibility genes; however, other genes, mostly within the major histocompatibility complex (MHC) region, confer an independent risk for PsA. The human leukocyte antigen-C0602 allele confers the highest risk for psoriasis whereas several human leukocyte antigen-B alleles were identified as 'PsA-specific' genes. Fine mapping of the MHC suggests that glutamine at position 45 is an important susceptibility factor for PsA. Additional genes outside of the MHC region were identified as psoriasis susceptibility genes. These genes belong to several proinflammatory pathways and skin barrier mechanisms that play a role in the pathogenesis of psoriatic disease. SUMMARY: The MHC remains the major susceptibility locus for psoriatic disease. Future studies using next-generation sequencing technologies may reveal novel rare susceptibility genes for this disease.

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.
