Overview
- A genome-wide association study (GWAS) identified a genetic variant near the FOXP4 gene that increases susceptibility to long COVID by approximately 60%.
- The study analyzed data from 6,450 long COVID cases and over one million controls across 24 studies in 16 countries, with findings confirmed in a replication cohort of 9,500 cases.
- FOXP4, a gene critical to lung development and function, is implicated in long COVID through potential disruptions in lung repair and immune responses.
- The research, published in *Nature Genetics*, was led by teams at Karolinska Institutet in Sweden and the Institute for Molecular Medicine Finland.
- This discovery lays the groundwork for precision medicine approaches, including risk stratification and targeted therapies for individuals with long COVID.
