18 Nine different polymorphic loci in the â2AR gene have been identified, of which four change the amino acid sequence of the â2AR protein: Arg16 Gly, Gln27 Glu, Val34 Met and Thr164 Ile [12]. Login to comment
20 The only genetic variant that leads to a decreased binding of agonist is the Thr164 Ile polymorphism which is rare (, 5%) and has been found only in heterozygous form [12]. Login to comment
32 Subjects were analysed according to their genotype for the Arg16 Gly, Gln27 Glu and Thr164 Ile alleles. Login to comment
33 Patients with the genotype Arg16 Arg, Gln27 Gln and Thr164 Thr carry the wild-type alleles, Arg16 Gly, Gln27 Glu and Thr164 Ile are heterozygous for the alleles and individuals with the Gly16 Gly or Glu27 Glu genotype are homozygous for the respective polymorphic allele. Login to comment
45 The primers used for detection of the Thr164 Ile polymorphism were forward primer (59- GTGATCGCAGTGGATCGCTACT-39) and reverse primer (59-AGAGCAAGACCATGATCACCAG-39), and an annealing temperature of 58 8C was used. Login to comment
76 The frequency of the Thr164 Ile polymorphism is below 5% within different populations [10,11,14] and, in our study, was only detected in four cystic fibrosis patients in heterozygous form. Login to comment
83 Isoproterenol-stimulated cAMP formation, expressed as percentage of basal stimulation, was significantly decreased in patients heterozygous for the Thr164 Ile polymorphism compared to four subjects homozygous for Arg16 , Gln27 and Thr164 (P ¼ 0.0013) (Fig. 3). Login to comment
84 cAMP formation in subjects double-heterozygous for Arg16 Gly and Gln27 Glu was similar to that of subjects who had the Thr164 Ile polymorphism (Fig. 3). Login to comment
104 Similarly, patients homozygous for the Thr164 allele have significantly higher values for FVC, FEV1 and MEF50 when compared to heterozygous allele carriers (Thr164 Ile). Login to comment

2274 Several of these SNPs alter the protein structure by causing a change in amino acid: Arg16Gly, Arg19Cys, Glu27Gln, Val34Met, and Thr164Ile (Hall, 2006). Login to comment
