Abstract The wide variety of new HIV-1 recombinant variants are a predominant challenge for understanding the molecular epidemiology and preventing the spread of the HIV-1 epidemic. In this study, we confirmed a novel HIV-1 unique B/C recombinant (ZLQ01186) isolated from a male patient infected with HIV-1 through injection drug use in Foshan city, Guangdong Province. The near full-length genome was amplified, and then the polymerase chain reaction products were sequenced by Sanger sequencing. The genomic sequence of the strain, with two subtype B segments inserted into the subtype C backbone, was 8,953 bp in length, extending from 647 to 9,599 bp according to the HXB2 genome. In addition, this B/C recombinant strain contained the non-nucleoside reverse transcriptase inhibitor resistance mutation K103N and the integrase strand transfer inhibitor other resistance mutation L74I according to the Stanford University HIV Drug Resistance Database program. The drug resistance profile indicates high-level resistance against efavirenz and rilpivirine. This study identified a recombinant between the main circulating strains, indicating a more complicated trend of the HIV-1 epidemic in Guangdong, China.

Mutation Information
Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
