Combination analysis of ADRB2 Arg16Gly polymorphism and EHI% may predict the effectiveness of β<sub>2</sub>-adrenergic receptor agonist treatment in patients with COPD and emphysema.
This study was conducted to assess the genetic association between Arg16Gly and Gln27Glu polymorphisms and COPD in the Egyptian patients, and to analyze their impact on the clinical outcome and therapeutic response.
The aim of this research was to verify if p.Arg16Gly (c.46A > G) and p.Gly27Glu (c.79G > C) single nucleotide polymorphisms (SNPs) exert a negative effect on the selected clinical indicators of COPD.
We did a prespecified analysis of the ADRB2 polymorphisms Arg16Gly and Gln27Glu within the 1 year randomised, double-blind, double-dummy, parallel-group Prevention Of Exacerbations with Tiotropium in COPD (POET-COPD) trial, comparing the effects of treatment with tiotropium or salmeterol on exacerbations in 7376 patients with COPD.
We tested the hypothesis that three functional polymorphisms in the ADRB2 gene (Thr164Ile, Gly16Arg and Gln27Glu) are associated with reduced lung function, asthma or chronic obstructive pulmonary disease (COPD).
We hypothesised that β<sub>2</sub>-adrenergic receptor genotypes, Gly16Arg (rs1042713, c.46G>A) and Gln27Glu (rs1042714, c.79C>G) influence risk of severe exacerbations in COPD.

We tested the hypothesis that three functional polymorphisms in the ADRB2 gene (Thr164Ile, Gly16Arg and Gln27Glu) are associated with reduced lung function, asthma or chronic obstructive pulmonary disease (COPD).
Eighty-two patients with COPD and 17 healthy smokers were recruited and screened for ADRb2 (T164I and R175R), for CHRM2 (rs1824024) and for CHRM3 (-513C/A and -492C/T).
Finally, we found that the rare Thr164Ile polymorphism in ADRB2 was associated with reduced lung function and risk of COPD, whereas the more common Gly16Arg and Gln27Glu were not.
