Abstract

Background:

The interleukin-13 (IL-13) gene has been associated with allergic asthma pathogenesis due to its role in IgE synthesis. The IL-13 single nucleotide polymorphism (SNP) rs1800925 has been implicated in exacerbated allergic asthma symptoms in different ethnicities.

Objectives:

To determine the association of IL-13 SNP rs1800925 with allergic asthma symptoms in the Asian population.

Methods:

Major databases were searched for studies on the association of IL-13 rs1800925 with allergic asthma in various Asian populations published between 2010 and February 2022. The odds ratio with 95% CI was obtained from included studies, and the association was evaluated using different genetic models. Heterogeneity was explored by subgroup analyses and I² statistic evaluation.

Results:

Eleven studies with a total of 2895 cases and 2914 controls were included in this meta-analysis. The majority of the cases exhibited CC genotype (n = 1897), followed by CT genotype (n = 852), and TT genotype (n = 146). IL-13 rs1800925 was significantly associated with increased allergic asthma risk in the Asian population under the recessive model (TT vs CT/CC: OR, 1.48; 95% CI, 1.14-1.93; P = 0.37; I² = 08%). Subgroup analyses by ethnicity showed an elevated risk of allergic asthma in West Asians (Iranian and Saudi Arabian) followed by East Asians (Chinese and Japanese) using the recessive model. Both age groups (adults and children) exhibited an increased risk of allergic asthma.

Conclusion:

This meta-analysis provides evidence that IL-13 SNP rs1800925 is a risk factor for allergic asthma in the Asian Population. It also suggests that rs1800925 is a risk factor present in both adult and children population.

Genome-wide Association Studies-GWAS

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...

Exon Recombination

Exon Recombination

The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...

Asthma-I: Introduction

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma: Pathogenesis and Management

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
