Asthma Runs in Families — But Genes Are Only Part of the Story
Twin studies show a strong inherited component to asthma liability while also demonstrating that infections, exposures and individual environments matter.

Twins can help researchers study whether early respiratory infections and later asthma share causes, consequences or both—but timing alone does not prove causation.
Asthma Changes Over Time: What Longitudinal Twin Research Can — and Cannot — Untangle
Twin cohorts show that genetic and environmental contributions can look different by age and phenotype. Longitudinal data help explain persistence without turning stress or any single exposure into a personal cause.
