To conduct a randomized trial in asthmatic children to compare the effectiveness of a home-based allergen control program with a customary educational program delivered in offices
To conduct molecular genetic studies in human pedigrees in order to identify the major genes responsible for asthma.
To identify clinical predictors of episodes of hospital-based care in people with asthma.
