Genetic epigenetic-clock scores and head and neck cancer risk in a case-control study
In 2189 head and neck squamous cell carcinoma cases and 2189 matched controls, higher polygenic scores for four epigenetic clocks were linked to higher cancer risk; Mendelian randomization suggested possible causal effects for HannumAge and GrimAge. [1]

Matched HNSCC case-control with clock polygenic scores
The study used a large case-control design with 2189 head and neck squamous cell carcinoma (HNSCC) cases and 2189 controls matched by age and sex. Genetic variants identified in genome-wide association studies for four epigenetic clocks (HannumAge, HorvathAge, GrimAge and PhenoAge) were combined into clock-specific polygenic scores. Logistic regression tested whether these scores were associated with HNSCC risk.

Higher clock scores, higher HNSCC risk
Polygenic scores for all four clocks were higher in cases than controls. Each standard deviation higher HannumAge score was associated with 25% higher HNSCC risk (odds ratio 1.25, 95% confidence interval 1.10–1.41); the other three clocks showed weaker positive associations (odds ratios 1.06–1.10). People in the highest score quartile for all four clocks had 14%–25% higher risk than those in the lower three quartiles.

Mendelian randomization hints at possible causal roles
Two-sample Mendelian randomization supported potential causal effects of genetically predicted HannumAge (odds ratio 1.24 per standard deviation, 95% confidence interval 1.09–1.42) and GrimAge (odds ratio 1.23, 95% confidence interval 0.98–1.56) on HNSCC risk, with consistent estimates in weighted median analyses. The GrimAge interval included 1.0. The authors describe biological aging as a potential etiologic mechanism and suggest clock-related genetic profiles might improve risk stratification.

How to interpret this
Abstract only; the full text was not reviewed. The design is a case-control study plus two-sample Mendelian randomization, so associations are not proven causes. The GrimAge causal estimate had a confidence interval including 1.0, and the abstract reports no follow-up or replication details.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
