Insights

Genetic variations in ACSM4 are linked to faster AIDS progression in untreated HIV patients. Specific ACSM4 genotypes and haplotypes increased the odds of rapid disease advancement, suggesting a role in HIV-1 pathogenesis.

Area of Science:

  • Genetics
  • Immunology
  • Virology

Background:

  • Human Immunodeficiency Virus (HIV) infection leads to Acquired Immunodeficiency Syndrome (AIDS).
  • Genetic factors may influence the rate of disease progression in untreated individuals.
  • ACSM4 and PECI gene polymorphisms are investigated for their potential role in AIDS progression.

Purpose of the Study:

  • To investigate the association between ACSM4 and PECI gene polymorphisms and the rate of AIDS progression.
  • To identify genetic markers that predict rapid disease progression in treatment-naive HIV-infected patients.

Main Methods:

  • A cohort of 454 HIV-infected patients with no prior antiretroviral therapy was studied.
  • Patients were categorized into long-term nonprogressors, moderate progressors, and rapid progressors.
  • Genotyping for specific ACSM4 (rs7137120, rs7961991) and PECI polymorphisms was performed.

Main Results:

  • Specific genotypes of ACSM4 (rs7137120 AA/AG and rs7961991 CC/CT) were associated with a significantly higher odds of rapid AIDS progression.
  • An ACSM4 haplotype (rs7961991 A and rs7137120 C alleles) also showed increased odds of rapid progression.
  • No significant associations were found for PECI polymorphisms with AIDS progression.

Conclusions:

  • ACSM4 polymorphisms appear to play a significant role in modulating the rate of AIDS progression in untreated HIV-infected individuals.
  • These findings may contribute to understanding the genetic determinants of HIV disease course.
  • Further research is warranted to elucidate the functional mechanisms of ACSM4 in HIV pathogenesis.

Retrovirus Life Cycles01:10

Retrovirus 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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
