Method: Briefly, mutation-specific primer
Result: In one case, six mutations,
M41L,
K70R,
M184V,
M46I,
M46L and
L90M were detected as minority mutations by the highly sensitive assays (ID 29).
Result: The sensitive screening detected an additional one case of
M41L (0.67%), two cases of
K65R (1.34%), two cases of
K70R (1.34%), one case of
M184V (0.67%), 15 cases of
M46I (19.46%), 5 cases of
M46L (3.36%) and 4 cases of
L90M (2.68%) as minority-level drug resistance mutations (Table 2).
