What is Asthma?

There are more than five chromosomal regions linked with asthma. The relative roles of genes at these locations are not clear, but genes on chromosome 5 and chromosome 20 are promising areas for investigation. Asthma is a chronic lung disease that causes the lining of a person's airways to swell, tighten and inflame when exposed to different irritants or triggers.
