Asthma is a common respiratory condition with approximately 55–75% heritability. Genetic factors affecting airway inflammation and immune responses are key.
How Genetic Is Asthma?
Genetics plays a meaningful role in Asthma, with heritability estimated at around 55%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Asthma: IL13,ORMDL3,GSDMB,PHF11. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
