HIV variants carry natural polymorphisms related to drug resistance (R-markers) fixed during viral evolution in the absence of antiretroviral therapy (ART) that may impact on drug susceptibility and resistance pathways. We aimed to identify the HIV type 2 (HIV-2) variant-specific R-markers at Pol in all available sequences from ART-naive subjects deposited in Los Alamos database according to reported HIV-2 drug resistance-associated mutations (DRMs) and report the performance of two online HIV-2 resistance interpretation tools (HIV2EU Tool and Stanford HIVdb Program for HIV-2) to detect them. From a total of 587 sequences, we found 23 R-markers in low frequency, in groups A, B, and G. Four were present in >10% of the sequences with no direct impact on antiretroviral susceptibility. HIV2EU Tool detected one, whereas Stanford program all four. Stanford new tool, although still under development, seems effective in detecting HIV-2 DRMs and may prove a useful tool for HIV-2 resistance interpretation when fully developed.
