Abstract Background In vitro and some in vivo studies suggested that genetic haplotypes may have an impact on P2-agonist mediated airway responses in asthmatics. Due to strong linkage disequilibrium the single nucleotide polymorphisms SNPs in the P2-adrenoceptor gene result in only a limited number of haplotypes. We intended to evaluate the impact of P2-adrenoceptor haplotypes on P2-agonist mediated airway responses and the development of tolerance in mild to moderate asthmatics. Methods Patients were genotyped for the part of the P2-adrenoceptor .
