Which type of gene could be considered a "candidate gene" for mutations that increase the genetic input to asthma development?

Question

Quizplus · Accepted Answer

A gene that regulates the sensitivity of bronchiolar smooth muscle could be a candidate gene for mutations that increase the genetic input to asthma development. Asthma is characterized by airway inflammation and bronchoconstriction, which are caused by the contraction of bronchiolar smooth muscle. Mutations in a gene that regulates the sensitivity of this smooth muscle could lead to increased bronchoconstriction and, thus, an increased risk of developing asthma. The other choices are not directly related to asthma development.
