Variant Details

Showing all: 1 variant(s).

Variant ID.  1020
Epitope Seq.  RLRPGGKKK
Variant Seq.  RLRPGGKKh
Mutations K/H
Epitope Location K9H
HXB2 Location K28H
Mutation Type DR: diminished response
Epitope Subtype B
Variant Subtype C
Method CD8 T-cell Elispot - IFNy
Note Cross-recognition of the variant is seen with both C- and A-clades. The C-clade variant contains a change at position 9 to RLRPGGKKh. Typically, magnitude and avidity of binding for T-cell responses were much lower to the C-clade variant.
