The analysis of a pol gene fragment encoding protease and part of reverse transcriptase was carried out for 55 sera collected in 2016 and 2018 from HIV-1-infected patients diagnosed in 2014–2018 living in the south of Western Siberia, Russia: Altai Territory (n = 11), Republic of Altai (n = 15), Kemerovo region (n = 18), and Novosibirsk region (n = 11). CRF63_02A was the dominant genetic form (>70%) in the Altai Territory and Kemerovo and Novosibirsk regions, with subsubtype A6 comprising <30% of samples. In the Altai Republic, subsubtype A6 was predominant (53%), with 33% of viruses belonging to CRF63_02A. Four CRF63_02A/A6 unique recombinant forms were identified in the Altai Territory, Kemerovo Region, and the Altai Republic. A majority (11 of 15) of CRF63_02A viruses from Kemerovo were grouped in a cluster. Antiretroviral (ARV) drug resistance mutations were found in 6 (14%) of 43 drug-naive patients. This study provides new insights in HIV-1 molecular epidemiology and prevalence of transmitted ARV drug resistance mutations in Southwestern Siberia.
