Variant Details

Showing 1 of 2 variants.

Variant ID.  1572
Epitope Seq.  RLRPGGKKKY
Variant Seq.  RLRPGGKKrY
Mutations K/R
Epitope Location K9R
HXB2 Location K28R
Mutation Type DR: diminished response
Method CD8 T-cell Elispot - IFNy, Sequence
Note This variant from the HXB2 sequence was present in the restricting HLA-A30 allele carrying mother, M-1002, as well as her HLA-A30-carrying infant, P-1031. Decreased recognition of the variant was seen relative to index epitope in the mother. The variant was detected at decreasing frequencies by 11 months of age in infant P-1031, but recognition was equivalent to index epitope recognition in the infant.
