Insights

Investigating the prothrombin (FII) gene

Area of Science:

  • Genetics
  • Hematology
  • Molecular Biology

Background:

  • Thrombophilia is a complex disorder with both genetic and acquired risk factors.
  • Idiopathic thrombophilia, where the cause remains unknown, presents a challenge in understanding disease etiology.
  • The 3' end of the prothrombin (FII) gene is a potential site for gain-of-function mutations.

Purpose of the Study:

  • To screen the 3' end of the prothrombin (FII) gene for variants in patients with idiopathic thrombophilia.
  • To assess the role of identified gene variants in the pathogenesis of thrombophilia.

Main Methods:

  • DNA sequencing was used to analyze a 715 bp region at the 3' end of the FII gene.
  • The study included 100 patients with idiopathic thrombophilia and 100 healthy controls.

Main Results:

  • Two variants, A19911G and C20068T, were detected in the prothrombin gene.
  • The A19911G variant showed no statistically significant difference in frequency between patients and controls.
  • The C20068T variant was more frequent in patients (4.0%) than controls (1.0%), but this difference was not statistically significant.

Conclusions:

  • The A19911G variant is unlikely to be a significant risk factor for idiopathic thrombophilia.
  • The C20068T variant may represent a potential risk factor, warranting further investigation.
  • Larger cohort studies are needed to confirm these findings and establish the role of FII gene variants in thrombophilia.

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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

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...
