Introduction. ADAM33 is the candidate gene most commonly associated with asthma and airway hyperreactivity (AHR). Aim. The aim of this study was to determine whether level of AHR is associated with certain alleles or haplotypes of the ADAM33 gene in asthmatic children. Methods. One hundred and nine asthmatic children and 46 controls from the general population were examined with spirometry before and after histamine and methacholine inhalation. All subjects were genotyped for single-nucleotide polymorphisms (SNPs) of the ADAM33 gene. Haplotypes were determined according to genotypes of the patient's parents. Results. We found the three most frequent ADAM33 haplotypes (a1-3) were associated with the highest level of AHR to methacholine and histamine in 66% of asthmatic children. The paternally transmitted GGGCTTTCGCA haplotype was seen in 73.3% asthmatic children with serious AHR to methacholine challenge (paternal and maternal origin of haplotype 73.3% to 37.5, P=0.046) Significant differences in the relative frequency of paternal haplotypes with high levels of AHR to histamine were found (P=0.013). Conclusion. ADAM33 haplotypes (a1, a2, a3) are associated with severity of AHR and are significantly more often transmitted in the paternal line.
