Short communicationHuman leukocyte antigen-associated gag and nef polymorphisms in HIV-1 subtype A/E-infected individuals in Vietnam

Numbers of HLA-associated polymorphisms have been reported on HIV-1 subtypes B and C, but few on other subtypes. Here, we analyzed HLA-associated gag and nef polymorphisms in HIV-1 subtype A/E prevalent in Vietnam. We determined HLA-A, B and C genotypes in 179 HIV-1-infected Vietnamese by next generation sequencing and analyzed proviral genome sequences in 144 of them, showing that 142 of the 144 were subtype A/E. Analysis revealed HLA-associated subtype A/E gag and nef polymorphisms at nineteen residues including those newly determined. Accumulation of these data would contribute to our understanding of HIV-1 subtype A/E and host immune interaction.
