A recent meta-analysis incorporating 6 independent studies of children and adults [5-10] reported that the A allele of IL13 single nucleotide polymorphism (SNP) rs20541 (Arg110/130Glu) in the coding region of exon 4 was associated with an increased risk of allergic rhinitis whereas IL13 SNP rs1800925 (-1024C/T) in the promoter region was not related to the risk of allergic rhinitis [11]. The gene discussed is IL13; the disease is allergic rhinitis.
