Asthma genetics is the study of genetic factors that contribute to the development and progression of asthma, a chronic respiratory condition characterized by inflammation and narrowing of the airways. Researchers in this field investigate the role of genetic variations in increasing susceptibility to asthma, as well as the genes involved in regulating immune responses and airway inflammation. By identifying genetic markers associated with asthma, researchers hope to better understand the underlying mechanisms of the disease and develop more targeted and personalized treatments for individuals with asthma.
