Genetic Characteristics of HIV-1 CRF12_BF First Identified in Guangdong Province, China

AIDS Res Hum Retroviruses. 2021 Feb;37(2):157-161. doi: 10.1089/AID.2020.0193. Epub 2020 Sep 30.

Abstract

Multiple HIV-1 genotypes were found circulating in Guangdong Province, China, as this province is located in South China and has a high frequency of international trade. In this study, we report the near full-length genome (NFLG) of CRF12_BF that was identified from a male patient in Guangzhou city, Guangdong Province; this is the first time CRF12_BF has been reported in mainland China. The NFLG was amplified, and then PCR products were sequenced by Sanger sequencing. The CRF12_BF strain was confirmed by the Basic Local Alignment Search Tool and a neighbor-joining phylogenetic tree. In addition, this CRF12_BF strain was confirmed to contain the non-nucleoside reverse transcriptase inhibitor mutation E138A associated with potential low-level resistance against efavirenz and low-level resistance against rilpivirine by the Stanford University HIV Drug Resistance Database program. The analyzed sequence data in this study will provide more information on the HIV epidemic in China.
