Abstract: The unexpectedly high percentage of drug resistance in Henan province is mainly due to the prevalence of minor mutations in the protease and integrase regions, especially A71T/V and L68V/I/IM/LV.
Characteristics of HIV-1 natural drug resistance-associated mutations in former paid blood donors in Henan Province, China.
Discussion: Results from the HIV-1 drug resistance mutation research by the International AIDS Society-USA (updated in March 2013) have revealed that PI resistance mutation sites are L10I, K20M, V32I, M36I, M46I/L, I47V/A, I50V, Q58E, A71V, G73S, V82A/F/T, I84V, L89V,L90M; NRTIs resistance mutations are M41L, A62V, PMID: 24629078

Result: According to the IAS-USA, the mutations associated with drug resistance, with a p >10%, were L10I, M36I, I62V, L63P, I64V, A71V/T, V77I, L90M, and I93L.
The prevalence of transmitted HIV drug resistance among MSM in Anhui province, China.
Result: However, some accessory mutations that did not affect susceptibility to ARV drugs were found in the protease gene, including L10I/L/V (3.0%; 4/133), V11I/V (3.0%; 4/133), L33F (2.3%; 3/133), and A71A/V/T (12.8%; 17/133).
Discussion: Other commonly observed mutations were T69A/N/S, V179E, L10I/L/V, V11I/V, L33F, and A71A/T/V; none of these mutations is known to confer drug resistance to NRTIs, NNRTIs, or PIs.
Discussion: The prese

Abstract: Herein, we extend our analysis, which includes seven double (G48V-V82A, L10I-G48V, G48V-L90M, I84V-L90M, L10I-V82A, L10I-L63P, A71V-G73S) and four multiple (L10I-L63P-A71V, L10I-G48V-V82A, G73S-I84V-L90M,
Structural basis and distal effects of Gag substrate coevolution in drug resistance to HIV-1 protease.
Abstract: To understand the molecular basis of this protease-substrate coevolution, we solved the crystal structures of drug resistant I50V/A71V HIV-1 protease with p1-p6 substrates bearing coevolved mutations.

Abstract: Three minor protease resistant-conferring mutations (A71AT, A71V, A71T) and five mutations conferring high to low-level resistance (K219EK, T69S, K103S, G190A and K103N) were detected in the RT region.
Persistence of frequently transmitted drug-resistant HIV-1 variants can be explained by high viral replication capacity.
Result: PI mutations included L10I/V (7.2%, 16/223) and A71L/T/V (6.3%, 14/223), with relatively high frequency; NRTI mutations, included L74I (0.45%, 1/223) and V75L (0.45%, 1/223); and the most frequent NNRTI mutation was V179D/E (5.4%, 12/223).
Result: Among CRF07_BC recombinant strains, 21.0% (13/62) had TDR-associated mutations, A71T/V being the most frequent.
Result: Among subtype B, 54.5% (12/22) had TDR-associated mutations, A71T/V and V106I being the most frequent.
