Insights

The transforming growth factor-β1 (TGFB1) gene -509C/T polymorphism is associated with increased risk of moderate-to-severe allergic rhinitis (AR) in children. This genetic variation may influence childhood persistent AR severity.

Area of Science:

  • Genetics
  • Immunology
  • Pediatrics

Context:

  • Allergic rhinitis (AR) is a common chronic condition in children.
  • Genetic factors are known to influence AR susceptibility and severity.
  • The transforming growth factor-β1 (TGFB1) gene plays a role in immune regulation.

Purpose:

  • To investigate the association between the TGFB1 gene promoter polymorphism -509C/T and the disease severity of childhood persistent allergic rhinitis.
  • To explore potential genetic markers for predicting AR severity.

Summary:

  • A study of 96 Chinese children with persistent AR analyzed the TGFB1 -509C/T polymorphism using PCR-RFLP.
  • Patients with the TT genotype showed a significantly increased risk for moderate-to-severe AR compared to CC/CT genotypes.
  • Serum total IgE and eosinophil cationic protein (ECP) levels were associated with the polymorphism, but not TGF-β1 levels.

Impact:

  • The TGFB1 -509C/T polymorphism may serve as a potential genetic indicator for AR severity in pediatric populations.
  • Findings contribute to understanding the genetic underpinnings of allergic diseases.
  • This research may inform future personalized treatment strategies for childhood allergic rhinitis.

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...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

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...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
