Abstract: Study samples (n = 363) collected between 1991 and 1997 from patients exposed to two or more
nucleoside analogue reverse transcriptase inhibitors (
NRTIs) and 274 control samples from patients exposed to no or one
NRTI were screened for two marker mutations of multinucleoside resistance (the
Q151M mutation and a mutation with a 2-amino-acid insertion at codon 69,
T69S-XX).
Abstract: and
T69S-XX was identified in two of the study samples (0.5%; both of them
T69S-SS), but both patterns were absent among control samples.
