Association of Interleukin-28B Polymorphisms (rs12979860 C/T, rs12980275 A/G, rs8099917 T/G) and Risk of...

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. The association of interleukin 28B (IL-28B) polymorphisms and HCC has been investigated in several populations. However, the findings are controversial. This study aimed to address the association between IL-28B polymorphisms (rs 8099917 T/G, rs12979860 C/T, rs12980275 A/G) and the risk of HCC in an Iranian population. METHODS: We have evaluated the association between IL-28B polymorphisms (rs 8099917 T/G, rs12979860 C/T, rs12980275 A/G) and HCC in 180 Iranian individuals (60 patients with HCC and 120 healthy matched controls) using polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) method. Single nucleotide polymorphism (SNP) association analysis and also haplotypes were estimated using the SNPstats online software. RESULTS: There was no significant association between these three polymorphisms of IL-28B and HCC (P>0.05). Moreover, haplotype analysis showed no significant association between the haplotypes and HCC. CONCLUSION: There was no association between IL-28B polymorphisms and HCC in an Iranian population.
