New Genetic Links Between Height and Disease Uncovered
In a groundbreaking study published in npj Genomic Medicine, researchers have identified significant genetic links between an individual’s genetically predicted height and their likelihood of developing various diseases. This discovery could pave the way for improved early diagnosis and risk monitoring for patients worldwide.
The study, led by an international team of scientists from Queen Mary University of London, utilized data from six diverse ancestry cohorts—including European, African, East Asian, and Hispanic populations—to explore the relationship between genetically predicted height and health conditions. The researchers applied the Phenome-Wide Association Study (PheWAS) method, which examines a genetic score for height and its correlation with a wide range of diseases.
Key Findings of the Study
The study analyzed 1,768 traits across more than 800,000 individuals and found 254 statistically significant associations between genetically predicted height and disease risk. Some of the most notable findings included:
- A strong link between greater height and circulatory, endocrine/metabolic, and musculoskeletal disorders.
- The highest association observed between genetically predicted height and atrial fibrillation across all ancestries.
- Ancestry- and sex-specific variations in disease risk, such as a decreased likelihood of Hyperpotassemia in taller males but no significant association in females.
- Height-related mental health correlations, such as a reduced risk of anxiety disorders and post-traumatic stress disorder in taller males within the European ancestry group.
- A unique finding in female-only meta-analysis showing an association between increased height and benign neoplasm of the digestive system.
Dr. Areti Papadopoulou, the study’s first author and a postdoctoral research associate at the Medical Research Council Biostatistics Unit, emphasized the importance of these discoveries, stating, “We report associations with a series of disorders, involving mental disorders and the endocrine system, that have not been previously linked to genetically predicted height.”
Similarly, Dr. Eirini Marouli, the study’s senior author and associate professor in computational biology, highlighted the broader implications of these findings, noting, “Our research underscores the importance of inclusive genetic studies, which help us advance our understanding of health across populations and ensure scientific progress benefits everyone.”
Implications for Future Research
By incorporating diverse ancestries and sex-specific analyses, this research provides valuable insights into the underlying biological mechanisms linking height to disease. Such findings could help tailor preventive healthcare strategies, improve patient monitoring, and enhance personalized medicine approaches.
Conclusion
As the largest genetic study of its kind, this research marks a significant step forward in understanding how height influences health outcomes. Further studies are needed to explore the causal mechanisms behind these associations and to translate these insights into clinical applications.
