Abstract

Background: β2 adrenergic receptor (ADRβ2) polymorphisms including ADRβ2+46G.A have been reported to cause adverse outcomes in mild asthmatics. The extent to which ADRb2 polymorphisms and in particular their haplotypes contribute to severe asthma is unknown. Objective: To determine the association of ADRb2 polymorphisms and haplotypes with asthma severity. Methods: Caucasians (n = 2979) were genotyped for 11 ADRβ2 polymorphisms. The cohort (mean age 39.6, 60% female) included 2296 non-asthmatics, 386 mild asthmatics, 172 moderate asthmatics and 125 severe asthmatics. Haplotype frequency and haplotype pair for each subject was determined using the PHASE algorithm. Results: The three asthmatic cohorts were comparable in age and gender but were distinguishable from each other in terms of symptoms, spirometry, medication use and health care utilisation (p
