Epitope Alignment

Variants

RSLfNTVAvLY diminished HLA binding or increased off-rate; diminished response; escape documented in this paper

Epitope Name RY11

Species (MHC/HLA) human(A*02:01, A*30:02)

Variant Details

Showing 1 of 15 variants.

Variant ID.	`2978`
Epitope Seq.	`RSLYNTVATLY`
Variant Seq.	`RSLfNTVAvLY`
Mutations	Y/F T/V
Epitope Location	Y4F T9V
HXB2 Location	Y79F 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 RSLfNTVAvLY did not bind to HLA-A*02 in vitro, and it showed a significant decrease in ex-vivo EliSpot response in 1 chronically-infected, untreated patient; abrogation of CTL response in another such patient; with no changes in the third patient when compared to wt RY11. The authors designate Y79F and T84V mutation-containing peptides to be escapes.
