Insights

The methylenetetrahydrofolate reductase (MTHFR) gene 677T allele is likely not associated with coronary heart disease (CHD). This genetic variant was not found to be linked to CHD in the Chinese population studied.

Area of Science:

  • Genetics
  • Cardiovascular Disease Research
  • Molecular Biology

Context:

  • Coronary heart disease (CHD) is a significant global health concern.
  • Genetic factors play a role in CHD susceptibility.
  • The methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphism is a candidate genetic marker for various diseases.

Purpose:

  • To determine if the MTHFR gene C677T polymorphism is associated with coronary heart disease (CHD).
  • To investigate the genetic linkage between MTHFR C677T and CHD in a Chinese population.

Summary:

  • This study utilized transmission/disequilibrium tests (TDT, STDT, SDT) on 45 Chinese CHD pedigrees.
  • MTHFR genotypes were determined using PCR-RFLP.
  • No significant association was found between the MTHFR 677T allele and CHD.

Impact:

  • Suggests that the MTHFR 677T allele is probably not a risk factor for CHD in the Chinese population.
  • Contributes to understanding the genetic basis of CHD.
  • Informs future genetic association studies for CHD.

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...

Translation

Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.Translation Produces the Building Blocks of LifeProteins are called the...
