Insights

Genetic variations in the cyclooxygenase-1 (COX-1) gene were identified in pediatric patients with cardiovascular anomalies. These novel COX-1 gene variants may influence aspirin resistance and warrant further functional studies.

Area of Science:

  • Genetics
  • Cardiovascular Medicine
  • Pharmacogenomics

Background:

  • Aspirin resistance is a clinical concern linked to variations in the cyclooxygenase-1 (COX-1) gene.
  • Understanding COX-1 genetic variations is crucial for optimizing aspirin therapy, especially in pediatric cardiovascular patients.

Purpose of the Study:

  • To investigate and identify genetic variations within the coding regions of the human COX-1 gene.
  • To characterize novel polymorphisms in pediatric patients with cardiovascular anomalies.

Main Methods:

  • DNA sequencing was employed to screen the 4 coding regions of the COX-1 gene.
  • Genetic variants were identified in 90 pediatric patients and compared with an independent Caucasian population.

Main Results:

  • Twenty coding-region variants causing amino acid substitutions were identified.
  • Two novel non-synonymous polymorphisms (F200L and D189E) were discovered.
  • Several variants, including W8R and P17L, occurred at a frequency greater than 5%.

Conclusions:

  • Novel genetic variants of the human COX-1 gene have been identified in pediatric cardiovascular patients.
  • Further research is necessary to elucidate the functional significance of these COX-1 variants.

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...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Principles of Pharmacogenetics: Types of Genetic Variants

The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

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...

Pharmacogenetics of Phase I Enzymes: Cytochrome P450 Isozymes

Cytochrome P450 (CYP450) enzymes are a superfamily of heme-containing monooxygenases that play a pivotal role in Phase I drug metabolism by catalyzing oxidation and reduction reactions.These enzymes transform lipophilic xenobiotics into more hydrophilic metabolites, facilitating subsequent Phase II conjugation and eventual excretion. The CYP450 family is classified into families (e.g., CYP1–CYP3) and subfamilies (e.g., CYP2A, CYP2C), based on amino acid sequence homology.CYP450...
