HIV Mutation Detail Information

Virus Mutation HIV Mutation G140A


Basic Characteristics of Mutations
Mutation Site G140A
Mutation Site Sentence The E138K mutation, detected in five patients, was frequently observed in combination with other mutations, such as G140A, S147G, and Q148R, which are associated with integrase strand transfer inhibitor resistance. Similarly, the G118R mutation, also found in five patients, appeared in varied combinations, including with E138K and additional substitutions like R263K, Q146P, T66A, and T661.

Abstract The global HIV epidemic remains a major public health challenge, with DTG playing a key role in ART regimens due to its efficacy and tolerability. This study evaluated virological outcomes and resistance mutations in patients on DTG in Mozambique through a retrospective cohort study in seven DREAM centers. Data from 29,601 patients (98.1% on DTG) revealed a virological suppression rate of 95% (27,622/29,051). Factors positively associated with suppression included age > 50, longer ART duration, and being female. Of 17 resistance tests, 8 showed major mutations, including G118R and E138K. Results highlight DTG's effectiveness and the need for resistance surveillance.

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
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
Literature Information
  • Sequence Data: The study provides the data accession number.
