Summary
The A allele in the IL-18/-607 gene promoter region is linked to allergic rhinitis in Korean children. This finding suggests a genetic component in the development of this common inflammatory condition.
Area of Science:
- Immunogenetics
- Allergology
- Molecular Biology
Background:
- Allergic rhinitis is a prevalent chronic inflammatory condition with a known genetic predisposition.
- Interleukin-18 (IL-18), a pro-inflammatory cytokine, plays a significant role in immune responses.
Purpose of the Study:
- To investigate the association between IL-18/-607 promoter polymorphisms and allergic rhinitis in the Korean population.
- To explore the genetic underpinnings of allergic rhinitis susceptibility.
Main Methods:
- A prospective study involving 160 Korean children diagnosed with allergic rhinitis and 166 healthy controls.
- DNA analysis using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) to determine IL-18/-607 gene polymorphism.
Main Results:
- A statistically significant higher frequency of the AC genotype for the IL-18/-607 gene polymorphism was observed in children with allergic rhinitis compared to controls (P<0.05).
Conclusions:
- The A allele within the IL-18/-607 gene promoter region appears to be associated with an increased risk of developing allergic rhinitis in the Korean population.
- This genetic variation may contribute to the pathogenesis of allergic rhinitis.
