Summary
A standardized list of 80 drug-resistance mutations was developed to monitor transmitted HIV-1 resistance. This list ensures comparable estimates for genotypic surveillance, aiding treatment guidelines and prevention efforts globally.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- Monitoring transmitted HIV-1 drug resistance is crucial for effective treatment and prevention strategies.
- Current surveillance programs lack standardized criteria for defining transmitted resistance, hindering data comparability.
- Developing a consistent mutation list is essential for accurate epidemiologic estimates.
Purpose of the Study:
- To outline criteria for developing a standardized list of drug-resistance mutations for HIV-1.
- To establish a parsimonious and unambiguous list applicable to all Group M subtypes.
- To facilitate comparable genotypic surveillance of transmitted HIV-1 drug resistance.
Main Methods:
- Defined criteria for mutation selection: causality of resistance, development during therapy, absence as polymorphism, subtype applicability, and simplicity.
- Applied these criteria to identify mutations conferring resistance to protease inhibitors (PIs), nucleoside reverse transcriptase inhibitors (NRTIs), and non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Main Results:
- Developed a list of 31 PI-resistance mutations across 14 protease positions.
- Identified 31 NRTI-resistance mutations within 15 reverse transcriptase positions.
- Compiled 18 NNRTI-resistance mutations at 10 reverse transcriptase positions, totaling 80 mutations.
Conclusions:
- The developed list of 80 drug-resistance mutations provides a standardized tool for genotypic surveillance of transmitted HIV-1 resistance.
- Regular updates using consistent criteria are recommended to maintain the list's utility.
- This standardized approach will improve the comparability of resistance estimates worldwide.

00:36Viral Mutations
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...
01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
01:29Viruses with RNA Genomes
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...
01:26Size and Structure of Viral Genomes
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
