Which result of genetic/genomic variation has the most support as a cause of asthma?

Question

Quizplus · Accepted Answer

There is significant evidence to support the idea that genomic variation can lead to increased inflammatory responses to environmental triggers, which may be a major contributor to the development of asthma. This includes variations in genes responsible for regulating immune system signaling pathways, as well as genes involved in airway inflammation and reactivity. While other factors, such as early childhood exposures to inhalation irritants and decreased resistance to infectious microorganisms, may also play a role in asthma development, they are not as consistently linked to genetic or genomic variation. Option D (mutations of frontal lobe genes controlling attention-getting behavior) is not related to asthma at all.
