Summary
Identifying asthma susceptibility genes requires replication and functional data. This review highlights 22 additional genes with functional information, building upon previous research on genetic associations for asthma.
Area of Science:
- Genetics
- Immunology
- Respiratory Medicine
Background:
- Over 100 genes linked to asthma phenotypes, with 53 novel associations reported in 2006-2007.
- Replication and functional data are crucial for confirming asthma susceptibility genes.
- Previous reviews identified functional data for 40 polymorphisms; this work adds 22 more.
Purpose of the Study:
- To review and present functional information for additional candidate genes associated with asthma.
- To consolidate current knowledge on genes with both replicated genetic associations and demonstrated functional mechanisms for asthma.
Main Methods:
- Literature review of genetic association studies for asthma.
- Identification and compilation of studies reporting functional data for candidate asthma genes.
- Focus on genes with replicated associations and supporting functional evidence.
Main Results:
- 22 new genes with reported functional data for asthma-associated polymorphisms are identified.
- Key genes like filaggrin, interleukin-13, interleukin-17, and cysteinyl leukotriene receptor-1 are discussed.
- These genes show replicated associations and possess functional data supporting their role in asthma.
Conclusions:
- The number of asthma-associated genes with functional data continues to grow.
- Functional validation is essential for understanding the genetic basis of asthma.
- This review provides updated information on key genes contributing to asthma susceptibility.

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...
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.

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-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-IV: Diagnostic and Management
The diagnosis and management of asthma are comprehensive, encompassing clinical assessments, lung function tests, and pharmacological interventions. Here's an overview:
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
