Allele frequencies were similar between the cohorts (Chi-squared test; p>0.05) and genotypes were in Hardy–Weinberg equilibrium (p≥0.01). PIAMA: Prevention and Incidence of Asthma and Mite Allergy 15; PREVASC: Prevention of Asthma in Children 16, 17; KOALA: Child, Parent, Health, Focus on Lifestyle and Predisposition 18; IL: interleukin; UTR: untranslated region. I.I.: innate immunity website 26; lit: literature; HM: HapMap database 27. #: major alleles first, followed by minor alleles.
