Discussion: Common INSTI RAMS include R263K, Q148H/R/K, G118R, G140A/S/C, E138A/K/T, N155H, and Y143C/R.

Abstract: Both were superior to DTG, as evidenced by the data obtained with the IN mutant T66I/L74M/E138K/S147G/Q148R/S230N, which was selected by CAB using an EVG-resistant lab strain.
Virologic failure after 48 weeks of raltegravir-based regimen in low HIV-1 incidence setting.
Discussion: N155H was the main mutation pathway for virologic failure, followed by Q143R and Q148R/H mutation pathways.
Drug Resistance Mutations Against Protease, Reverse Transcriptase and Integrase Inhibitors in People Living With HIV-1 Receiving Boosted Protease Inhibitors in South Africa.
Discussion: N155H, Q148H/R/K, and Y143R/C/H are the three major recognized pathways of genotypic resistance against InSTIs.

Abstract: Predominant major mutations were N155H (35.1%), Q148H/R (15.8%) and G140A/S (14%).
Introduction: Different pathways against first-generation InSTIs were identified whose primary mutations include the substitutions N155H, Q148K/R/H, and Y143R/C.
Result: Predominant combinations of mutations were 140A/S + Q148H/R and N155H + G163K/R.
Result: Predominant major integrase resistance mutations were N155H (35.1%), Q148H/R (15.8%) and PMID: 30803972

Abstract: HIV-2 integrase mutants G140S/Q148R and G140S/Q148H were 34- and 110-fold resistant to bictegravir, respectively; other resistance-associated mutations conferred <=5-fold changes in bictegravir susceptibility.

Abstract: INSTI resistance changes were recognized in 12 patients: N155H (5), Q148H/R (3), Y143C/G (3) and R263K (1).
Predicted antiviral activity of tenofovir versus abacavir in combination with a cytosine analogue and the integrase inhibitor dolutegravir in HIV-1-infected South African patients initiating or failing first-line ART.

Abstract: One of 607 integrase sequences carried a DRM20% (Q148R).
Result: Among ART-exposed participants, only one had low-level resistance to dolutegravir (Q148R) among participants with available consensus sequence covering the integrase (n = 83).
Result: Fifteen participants had integrase DRM20% (15/83, 18.1%), including Q148R conferring low-level resistance to dolutegravir, and some accessory integrase mutations were also found: L74I/M (n = 12/15, 80.0%), E157Q (n = 1) and G163R (n = 1).
Discussion: We did observe Q148R, which is associated with high-level dolutegravir resistance

Introduction: DTG appears to have a high genetic barrier to resistance, unlike the other drugs within the INSTI class, raltegravir and elvitegravir, which select for major resistance mutations such as N155H, Y143H/R/C, G140A/S, and Q148H/R/K.
