Asthma, allergy, and airway hyperresponsiveness are not linked to the [β.sub.2]-adrenoceptor gene *. (clinical investigations)

Study objectives: To exclude genetic linkage between the [β.sub.2]-adrenoceptor gene and asthma, allergy, and methacholine airway hyperresponsiveness. Design: The current study used six distinct intragene markers within the [β.sub.2]-adrenoceptor gene, [...]
