Nasal Brush Identifies Genetic Biomarker of Asthma

Scientists at Mount Sinai say they have identified a genetic biomarker of asthma that can be tested for using a simple nasal brush and basic follow-up data analysis. This inexpensive diagnostic test can accurately identify mild to moderate asthma and differentiate it from other respiratory conditions, such as allergic rhinitis, smoking, upper respiratory infection, and cystic fibrosis, according to the team led by a collaboration of clinical and computational scientists in the Department of Gene
