Beta2 Adrenergic Receptor (ADRβ2) Haplotype Pair (2/4) Is Associated with Severe Asthma

摘要

Background β2 adrenergic receptor (ADRβ2) polymorphisms including ADRβ2+46G>A have been reported to cause adverse outcomes in mild asthmatics. The extent to which ADRβ2 polymorphisms and in particular their haplotypes contribute to severe asthma is unknown.
