CCR5-Δ32 is a functionally null allele of CCR5 gene with a 32-bp deletion. Several studies have reported that this mutation may be associated with recovery from acute hepatitis B or persistence of HBV infection. The main purpose of this study was to compare the frequency of the Δ32 mutation within the CCR5 gene in a group of chronic HBV infected patients with healthy individuals in Iran. Materials and Methods:A total of 200 blood samples including 100 healthy individuals and 100 HBsAg positive patients were randomly selected. The samples were tested for HBsAg by ELISA and HBV-DNA by PCR method. Genomic DNA was extracted by salting out method. CCR5-Δ32 mutation was genotyped by PCR with specific primers.  Results:The results of this study showed that none of the subjects in the control and patient groups had a 32-bp deletion in the CCR5 gene. CCR5-Δ32 was not a prevalent mutation in control group and HBV infected patients in Iran. Conclusion:No significant difference was observed in genotypes frequency of CCR5-Δ32 between control group and HBV infected patients, therefore it seems that this mutation is not associated with persistence of HBV infection in Iranian patients SP - 359 EP - 364 AU - Jalali, Sajjad AU - Sharifi, Zohreh AU - Sanati, Mohammad Hossein AU - Shahzadeh Fazeli, Abolhassan AD - Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran KW - CCR5 KW - Chronic hepatitis B KW - Mutation UR - http://koomeshjournal.semums.ac.ir/article-1-2182-en.html ER -
