A genome-wide study of the effect of alcohol consumption on the risk of type 2 diabetes
Bibliographic record
Abstract
The relationship between alcohol consumption and type 2 diabetes risk is often described as a J- or U-shaped curve, with moderate drinkers having a lower risk compared to non-drinkers and heavy drinkers. However, this protective effect appears to be more pronounced in women than in men, suggesting a potential interaction between sex-specific factors and alcohol metabolism. We conducted an interaction genome-wide association study (GWAS) to identify genetic variants that modify the relationship between alcohol consumption and type 2 diabetes risk in a sex-specific manner. We utilized data from the UK Biobank in a case-control approach including 309,568 individuals to investigate the three-way interaction between genetic variants, alcohol consumption, and sex on type 2 diabetes risk. We identified genetic variant rs78681203, located between the FOXO6 and EDN2 genes, with a significant sex-specific interaction with alcohol consumption (interaction p = 2.85 × 10 −8 ). The T allele of rs78681203 was associated with an increased risk of type 2 diabetes in women consuming 0 to <4 UK units/week (OR = 1.19, 95% CI: 1.07–1.34) but had a protective effect in women consuming 4 to <28 UK units/week (OR = 0.81, 95% CI: 0.69–0.95). Conversely, in men, the T allele was associated with a higher risk of type 2 diabetes in the 4 to <28 UK units/week group (OR = 1.19, 95% CI: 1.08–1.32) and had a protective effect in the 0 to <4 UK units/week group (OR = 0.85, 95% CI: 0.74–0.99). Our findings suggest that genetic variation may play a role in the differential effects of alcohol consumption on type 2 diabetes risk between men and women. Further replication and mechanistic studies are needed to confirm and clarify the role of the identified genetic variant. • Genetic variant rs78681203 interacts with alcohol consumption on sex-specific type 2 diabetes risk. • The T allele of rs78681203 protects women with higher alcohol intake from type 2 diabetes but increases risk in men. • rs78681203 is located between FOXO6 and EDN2, genes linked to glucose homeostasis and vascular function, respectively. • Genetic variation can help clarify alcohol’s differing effects on type 2 diabetes risk in men and women.

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.
