Abstract
BACKGROUND: Polysensitivity is defined as three or more positive patch test reactions. The role of filaggrin gene (FLG) loss-of-function mutations in patients with polysensitivity has not been studied when barrier bypass and possible preceding barrier damage have been excluded. OBJECTIVES: To determine whether FLG loss of function mutations play a role in patients with multiple contact sensitivities when barrier bypass is excluded. METHODS: One hundred and sixty-nine patients with three or more, non-cross-reacting, positive patch test reactions were prospectively enrolled in this study. Exclusion criteria were a history of hand dermatitis, nickel and metal implants, and stasis dermatitis. Subjects were patch tested with the North American extended patch test series, and with other relevant haptens. DNA was obtained and sequenced for the following FLG loss-of-function mutations: R501X, 2282del4, R2447X, and S3247X. RESULTS: One hundred and sixty-five patients were genotyped for the four FLG mutations. There was a significant association between R501X mutation and polysensitivity. For the other three tested mutations, there were no significant associations with polysensitivity. When all mutations were combined, there was a significant association between loss-of-function FLG mutations and polysensitivity in patients with a history of atopic dermatitis. CONCLUSION: When skin barrier bypass is excluded, there is a significant association between polysensitivity and FLG loss-of-function mutations.

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
