Influence of gene-by-sex interaction on time-to-asthma onset: a large-scale genome-wide meta-analysis
Bibliographic record
Abstract
<bold>Background:</bold> Asthma is a complex disease with sex-specific differences in prevalence, clinical and biological features. Asthma is more prevalent in males during childhood, while it becomes more frequent in females in adolescence and adulthood. The mechanisms behind these sex-specific differences are not well understood and may involve hormonal changes together with differential genetic predisposition. <bold>Objective:</bold> Our goal was to identify genetic variants interacting with sex that influence time-to-asthma onset (TAO). <bold>Methods:</bold> We conducted a large-scale meta-analysis of nine genome-wide interaction studies (GEWIS) of TAO (totaling 7,104 men and 6,970 females of European ancestry) using survival analysis methods applied to pediatric and adult asthmatic and non-asthmatic subjects. <bold>Results:</bold> We detected three independent loci showing SNP×Sex interaction at the 10<sup>-5</sup> level. The most significant association with TAO was female-specific in an intergenic region at 5q32 (P<sub>female</sub> = 9.1x10<sup>-8</sup> <italic>versus</italic> P<sub>male</sub>=0.56). The other two associations were male-specific: within <italic>SORCS2</italic> intron 2 at 4q16 (P<sub>male</sub>=1.3x10<sup>-7</sup> <italic>versus</italic> P<sub>female</sub>=0.15) and within <italic>DGKB</italic> intron 1 at 7p21 (P<sub>male</sub>= 3.9x10<sup>-7</sup> <italic>versus</italic> P<sub>female</sub>=0.23). Functional annotations indicated co-localization of these genetic variants with epigenetic marks and DNA regulatory elements in fibroblasts, lung or blood. <bold>Conclusion:</bold> By testing gene-by-sex interactions, we identified novel loci influencing asthma risk in a sex-specific manner. Candidate genes in these loci are involved in inflammatory process and immune cell regulation. Further replication of these findings are ongoing.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
