Showing all: 1 variant(s).

Variant ID.  4456
Epitope Seq.  LLIQNANPD
Variant Seq.  LLIQnANPD
Mutations N/n
Epitope Location N5n
HXB2 Location N325n
Mutation Type OV: observed variant
RCOK: replicative capacity is not abrogated
SF: susceptible form
Method CD8 T-cell Elispot - IFNy, Longitudinal study, Other, Relative replication capacity assay
Note Synonymous mutation N323tc appeared at 175d post-screening, and was fixed to completion (100%) by 670d post-screening, indicating strong selection. No T-cell- or Ab-responses were detected against the mutant, and it was not a cryptic epitope, showing host-specific, non-adaptive immune selection pressures. The mutant was not significantly less fit than T/F over 3 comparative passages.
