The importance of environment on respiratory genotype/phenotype relationships in the Inuit. Allergy 2010; 65 : 229–237. Abstract Background: Genetic and environmental influences and their interactions are central to asthma pathogenesis. This study aimed to investigate the effects of different macro‐environments on asthma genotype–phenotype associations in two geographically separated populations with common ancestry. Methods: To accomplish this, two unselected populations of Inuit were recruited, one living in Greenland ( n = 618) and the other in Denmark ( n = 739). Subjects were genotyped for CD14 C‐159T, SCGB1A1 A38G, ADRB2 Arg16Gly and Gln27Glu. The resulting genetic data were analysed for relationships with asthma‐related parameters including lung function, ever asthma, atopy, rhinitis and dermatitis. Results: The results showed contrasting magnitude and direction of genetic associations between the two geographically separate Inuit populations. In Greenland, the ADRB2 16Arg allele was associated with male‐specific lower lung function, but in Denmark the same allele was associated with male‐specific higher lung function. This allele was also associated with higher incidence of ever asthma in Denmark but not in Greenland. The SCGB1A1 38A allele was associated with lower rhinitis prevalence in Greenland but not in Denmark. Conclusions: These associations suggest that environment interacts with candidate asthma genes to modulate asthma pathogenesis in the Inuit.

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.
