Multi-trait and multi-ancestry genetic analysis of comorbid lung diseases and traits improves genetic discovery and polygenic risk prediction. - Nature genetics (2026) · He Y, Lu W, Jee YH, Shih MY, Wang Y, Tsuo K, Qian DC, Diao JA, Huang H, Patel CJ, Byun J, Pasaniuc B, Atkinson EG, Amos CI, Feng YA, Moll M, Cho MH, Martin AR · PubMed 41565855
While respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma share many risk factors, most studies investigate them in isolation and in predominantly European-ancestry populations. Here, we conducted the most powerful multi-trait and multi-ancestry genetic analysis of respiratory diseases and auxiliary traits to date, identifying 25 new loci associated with lung function in individuals of East Asian ancestry. Using these results, we developed PRSxtra (cross-trait and cross-ancestry), a multi-trait and multi-ancestry polygenic risk score (PRS) approach that leverages shared components of heritable risk via pleiotropic effects. PRSxtra significantly improved the prediction of asthma, COPD and lung cancer compared to trait- and ancestry-matched PRSs in a multi-an

Multi-ancestry genome-wide association analyses improve resolution of genes and pathways influencing lung function and chronic obstructive pulmonary disease risk - Unknown journal (n.d.) · Unknown authors · PubMed 36914875
ABSTRACT: Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 588,452 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of interve

Concrete actions anchored to the cited research. We do not prescribe, we describe.
Discuss with your doctor
-
GJA1 genetic predisposition to reduced lung function Moderate
GJA1 variant rs10456939 strongly associated with lower FEV1/FVC ratio; discussion enables personalized risk assessment and prevention.
Share genetic finding; discuss baseline spirometry timing, occupational/environmental exposures, and smoking prevention.
Lifestyle
-
Cigarette smoking and secondhand smoke Moderate
Genetic predisposition to reduced lung function amplifies harm from smoking-related airway damage.
Complete smoking cessation; minimize secondhand smoke and indoor air pollutant exposure.
Screening
-
Baseline spirometry and lung function testing Moderate
GJA1 rs10456939-A carriers show reduced FEV1/FVC ratio (GWAS p=4e-12, n=588k); baseline testing establishes personal lung function status.
Obtain baseline spirometry; discuss interpretation and repeat schedule with physician.
