A growing body of evidence suggests that many cell types present in asthmatic airways have the capacity to generate RANTES which directly supported the potential role of RANTES in asthma. A number of studies have evaluated the functional polymorphism -28C G in the RANTES promoter region which had been found to affect the transcription of the RANTES gene in relation to asthma susceptibility. However the results remain conflicting rather than conclusive. This meta-analysis on 1894 asthma cases and 1766 controls for -28C G from 9 published case-control studies showed that the variant allele -28G was associated with significantly increased risk of asthma GG CG vs CC OR 1.24 95 CI 1.08-1.41 without any be-tween-study heterogeneity. In the stratified analysis by asthma type age and ethnicity we found that the increased asthma risk associated with -28G C polymorphism was more evident in children OR 1.24 95 CI 1.06-1.45 Asian group OR 1.27 95
