Discussion: The mutations selected in the in vitro experiments confer cross-resistance to
NRTIs:
V75I contributes resistance to multiple
NRTIs in the presence of a concurrent
Q151M mutation,
T69N and other variants at position 69 are selected by didanosine and other
NRTIs but their susceptibility profiles are not well-described (http://hivdb.stanford.edu/), and the variants
M184I/V confer high-level resistance to lamivudine and emtricitabine.
