Variant Details

Showing 1 of 14 variants.

Variant ID.  3458
Variant Seq.  KgFSPEVIPMF
Mutations A/G
Epitope Location A2G
HXB2 Location A163G
Mutation Type LE: literature escape
RCR: replicative capacity reduced
SNSF: subtype-specific non-susceptible form
Epitope Subtype B, C
Variant Subtype B, C
Method CD8 T-cell Elispot - IFNy, Relative replication capacity assay, TCR binding
Note Escape variants A163G and S165N are selected in ˜70% of C-infected B*5703-positive subjects, but are not found in B-infected B*5703-positive subjects. The introduction of either or both of these mutations decreases viral replication. There were observable clade-specific differences between C-clade (Botswana) and B-clade (Barbados) 163G.
