Hypothesis

Is the ADAM33 gene associated with childhood asthma, lung function, and bronchial hyperresponsiveness?

Conclusion

The study could not confirm the previously reported association between ADAM33 polymorphisms and asthma, but suggests a complex role in non-atopic asthma.

Supporting Evidence

  • No single SNP showed a significant association with doctor's diagnosis of asthma.
  • A trend for more profound effects of ADAM33 SNPs was observed in individuals with asthma and bronchial hyperresponsiveness.
  • Haplotype analyses suggested a minor effect of the ADAM33 haplotype H4 on asthma.
  • Associations with non-atopic asthma and baseline lung function were identified.

Takeaway

Scientists studied a gene called ADAM33 to see if it affects asthma in kids, but they found it might not be as important as they thought.

Methodology

Genotyping of ten ADAM33 SNPs in 1,872 children from ISAAC II and 824 children from the MAS cohort.

Limitations

The study could not detect significant associations for many SNPs and the role of environmental factors was not established.

Participant Demographics

Children from two German populations, including asthmatics and non-asthmatics.
