Abstract excerpt
BACKGROUND/AIMS: We previously demonstrated that two linked single nucleotide polymorphisms (SNPs) at -408 and -3 of type I interferon receptor 1 (IFNAR1) promoter are associated with susceptibility to chronic HBV infection. We aimed to elucidate the mechanism by which -3 and/or -408 C/T SNPs had such profound effects. METHODS: A functional SNP in IFNAR1 promoter was defined by reporter gene assay, mutational...
