Background : Monocyte chemoattractant protein-1(MCP-1), one of the CC chemokines, appears to play a significant role in asthma pathogenesis. It was reported that polymorphism in the MCP-1(-2518 A/G promoter) was associated with asthma in Caucasians, but the association of this polymorphism and asthma patients in the Korean population has not yet been clarified.Objective : We investigated the possible association between 2 polymorphisms (-2518 A/G promoter and Cys35Cys) and asthma patients in a Korean population.Materials and Methods : DNA samples were obtained from 86 Korean asthma patients and 270 healthy controls. MCP-1 genomic variants (-2518 A/G promoter and Cys35Cys polymorphism) were detected by PCR-RFLP. Level of MCP-1 was measured by ELISA for each genotype (n=8) (AA, AG, GG) and allele types of -2518 A/G promoter polymorphism for control subjects.Results : The Cys35Cys polymorphism was associated with asthma patients in Korean population [genotype distribution (χ²=16.011, P<0.001)]. Comparison of the two groups revealed no detectable differences in genotype and allele frequencies of the -2518 A/G polymorphism. Haplotype frequencies analysis revealed significant difference (χ²=51.70, P<0.001). MCP-1 serum level of subjects with G genotype of -2518 A/G promoter polymorphism was statistically higher than that with AA genotype (P<0.05).Conclusion : Our data indicate that no association exists between the MCP-1 -2518 A/G polymorphism and asthma susceptibility in the Korean population. However, it is noteworthy that the high prevalence of the -2518 G allele in the Korean population suggests a potentially important ethnic variation in the regulation of MCP-1 production. This variation must be considered in gene-association studies in different ethnic populations.
