HLA-DPA1 and HIV infectious disease: Concerning the host genomic factor, several studies demonstrated by a genome-wide association study that single-nucleotide polymorphism (SNPs) in human leukocyte antigen (HLA)-DPA1 (rs3077) and HLA-DPB1 (rs9277535) loci are associated with HBV clearance in Asian people without HIV infection.[27,28] Therefore, we determined these SNPs in 19 cured and 11 chronic patients whose serum stocks were available with informed consent.
