Introduction: Several of these mutations, particularly
K101E/P and
M230L, have been associated with significant resistance to multiple
NNRTIs.
Discussion: covered the virus containing
K101E/
Y181C/
G190A and other mutations could increase 893-fold resistance to NVP.
Discussion: found the prevalence rate of
H221Y in isolates from patients failing NVP treatment was 10.3% and the mutation was included in the top 10 and 15 determinants for NVP and EFV resistance, respectively, ranking even above some classical
NNRTI resistance mutations, such as
K101E,
V108I, and
G190E.
