Discussion: The Sanger results of isolates from treated patients were as expected with a predominance of M184V, numerous TAMs of pathway1 (M41L, D67N, K70R, L210W, T215Y/F) and DRMs to NNRTIs (mainly K101E, K103N, V106M, Y181C, G190A).

Abstract: The most prevalent RT mutations were T215F/V/Y (66.7%), D67G/N (55.6%), K219Q/E/R (44.4%), M184V/I (38.9%), K70R/E (27.8%) and M41L (27.8%), associated with nucleoside reverse transcriptase inhibitors (NRTI) resistance; and K103N (55.6%), G190A (33.3%), and K101P/E/H (27.8%) associated with non-nucleoside reverse transcriptase inhibitors (NNRTI) resistance.
Minority variants associated with resistance to HIV-1 nonnucleoside reverse transcriptase inhibitors during primary infection.
Discussion: Y181C, K103N, G190A, H221Y, K101E, A98G, V108I, V106A, E138A, Y188L are the top ten most common mutations resistant to NVP in patients who received NVP treatment.

Result: Five additional viruses were predicted to be possibly resistant to ETV, including three viruses harbouring the E138A/G/Q/R DRM, one with the three DRMs K101E/H/I/P/R, Y181C, and G190A/S, and one with the three DRMs V90I, K101E/H/I/P/R, and G190A/S.
Result: Major NNRTIs DRMs were also obtained at positions P225H (n=12), K101E (n=11), Y181C (n=10), G190A (n=7), Y188L (n=6), V90I (n=5), PMID: 23236346

Result: The most frequent NNRTI mutations were K103N/S (27.8%), followed by Y181C (22.2%), V108I and G190A (16.7%), Y181V (11.1%), K101E and Y188L (5.6%) (Figure 2).

Genetic diversity and drug resistance among newly diagnosed and antiretroviral treatment-naive HIV-infected individuals in western Yunnan: a hot area of viral recombination in China.
Abstract: A total of 1.3% of DR were related to protease inhibitors (PIs), including I85IV, M46I and L90M; 0.3% to nucleoside reverse transcriptase inhibitors (NRTIs), including M184I; and 2.7% to non-nucleoside reverse transcriptase inhibitors (NNRTIs), including K103N/S
Result: Three individuals were found to have one other NNRTI-related mutation (K103NS, K101E and G190A) each (0.33%).
