Insights

Genetic variants in the CARD15 gene, known to influence Crohn's disease susceptibility, were investigated for their role in aggressive periodontitis. This study found no significant association between common CARD15 mutations and aggressive periodontitis risk.

Area of Science:

  • Genetics
  • Immunology
  • Periodontology

Background:

  • The CARD15 gene is crucial for innate immunity, acting as an intracellular receptor for bacterial products.
  • CARD15 gene variants are linked to increased susceptibility to Crohn's disease.
  • Aggressive periodontitis is a severe inflammatory condition affecting the gums and supporting bone.

Purpose of the Study:

  • To investigate the potential association between CARD15 gene variants and susceptibility to aggressive periodontitis.
  • To determine if genetic variations in CARD15 contribute to the development of aggressive periodontitis.
  • To compare the role of CARD15 variants in aggressive periodontitis with their known role in Crohn's disease.

Main Methods:

  • Direct sequencing of exons 4, 8, and 11 of the CARD15 gene.
  • Analysis of three main known CARD15 variants (p.R702W, p.G908R, and p.L1007fsX1008).
  • Comparison of allele frequencies in 86 generalized aggressive periodontitis patients and 67 healthy controls.

Main Results:

  • Low mutant allele frequencies for the three main CARD15 variants were observed in both patient and control groups, with no significant differences.
  • Specific rare variants (A755V and R791Q) were found in three aggressive periodontitis patients but not in controls.
  • The frequencies of common CARD15 variants did not differ significantly between aggressive periodontitis patients and healthy individuals.

Conclusions:

  • The study did not find an association between the three main CARD15 mutations and aggressive periodontitis susceptibility.
  • Unlike in Crohn's disease, CARD15 gene variants do not appear to play a significant role in aggressive periodontitis.
  • The clinical significance of rare CARD15 variants in aggressive periodontitis requires further investigation.

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...

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,...

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...

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...
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
