Variant ID.  1980
Epitope Seq.  ISPRTLNAW
Variant Seq.  lSPRTLNAW
Mutations I/L
Epitope Location I1L
HXB2 Location I147L
Mutation Type E: escape documented in this paper
Method CD8 T-cell Elispot - IFNy, Intracellular cytokine staining, Sequence
Note A simple but atypical pattern of escape was seen with this variant in one patient, CH77 where the variant completely replaced the index epitope. In patient CH58, no significant change with respect to selection in this epitope was detected. For CH58, positive ELISpot from the full proteome scan but with not statistical evidence for selection for change was seen. For CH77, known T cell response from the full proteome scan with evidence for variation and escape by positive ELISpot was seen.
