Variant Details

Showing 1 of 16 variants.

Variant ID.  1890
Variant Seq.  KgFkPEVIPMF
Mutations A/G S/K
Epitope Location A2G S4K
HXB2 Location A163G S165K
Mutation Type DHB: diminished HLA binding or increased off-rate
SNSF: subtype-specific non-susceptible form
SSF: subtype-specific susceptible form
Epitope Subtype B, C
Variant Subtype C
Method CD8 T-cell Elispot - IFNy, Chromium-release assay, Intracellular cytokine staining, Sequence, Tetramer binding
Note This variant is seen only in Clade C and binds HLA-B*5703. S164K variant is seen most frequently and is preferentially selected in context of HLA-B*5703. This A2G-S4K variant was recognized by HLA-B*5701- but not by -B*5703-expressing subjects, though avidity of recognition was reduced.
