Genetic variants of chemokine and regulatory cytokines play functional roles in chronic HBV infection. The objective of the study, was to evaluate the association between the CCR5D32 , CCR5 - 2459A / G , MCP - 1 - 2518A / G , VDR - APa1A / C , VDR - Taq1T /C SNPs and HBV susceptibility, in samples of Iranian populations. The CCR5D32 , CCR5 - 2459A / G , MCP1 - 2518A / G , VDR - APa1A / C , VDR - Taq1T / C polymorphisms were analyzed by polymerase chain reaction and PCR-RFLP using 100 chronic HBV infected (HBV) patients, 40 spontaneously recovered HBV (SR) subjects and 100 healthy controls (C). Also, serum levels of protein were monitored. The study showed that the existence of CCR5 - 2459A , MCP1 - 2518G and VDR - CC alleles significantly increased risk of chronic HBV infection. In addition, WtAGCC haplotype had a higher frequency in HBV patients than C and SR groups and might relate to the natural history of the infection. Statistical analysis indicated positive correlations between CCR5 - 2459A / G , MCP1 - 2518A / G , VDR - APa1A / C , VDR - Taq1T / C genotypes and serum levels of the CCR5, MCP-1 and VDR in HBV patients. According to the statistical analysis, significant associations with susceptibility to chronic HBV infection was observed with CCR5 - 2459A / G , MCP1 - 2518A / G , VDR - APa1A / C , VDR - Taq1T / C polymorphisms. In addition, no association of the CCR5D32 SNP with the disease was found.
