Summary Several lines of evidence suggest that chemokines play an important role in asthma and allergy. We analysed polymorphisms at -2518A/G and -2076A/T of MCP-1 and V64I of CCR2 gene in healthy subjects ( n = 306) and allergic patients ( n = 332). Allele and genotype frequencies did not differ significantly between groups. Nevertheless, MCP-1 variants were associated with allergen sensitization. The results suggest that MCP-1, but not CCR2 gene variants, may participate in the pathogenesis of allergic phenotypes at least in the Caucasian population
