Variant Details

Showing 1 of 15 variants.


Variant ID.  2975
Epitope Seq.  RSLYNTVATLY
Variant Seq.  RSLYNTiAvLY
Mutations V/I T/V
Epitope Location V7I T9V
HXB2 Location V82I T84V
Mutation Type DHB: diminished HLA binding or increased off-rate
DR: diminished response
E: escape documented in this paper
Epitope Subtype B
Variant Subtype B
Method CD8 T-cell Elispot - IFNy, HLA binding
Note Variant RSLYNTiAvLY did not bind to HLA-A*02 in vitro, and it showed complete abrogation of ex-vivo EliSpot responses in 1/3 chronically-infected, untreated patients; diminished response in another patient; and no change in the third as compared to WT RY11. The authors designate both V82I and T84V mutation-containing peptides to be escapes.
