Participants needed for collection of nasal cells

This study measures CFTR function in healthy controls, healthy cystic fibrosis (CF) carriers, and CF carriers with cystic fibrosis–like illness who are between age 5 and 80. Participants will have a five-minute nasal brushing performed at the Johns Hopkins Outpatient Center, a review of their medical history for CF-like illnesses, and saliva collection. They will be reimbursed for one meal and given a parking sticker.
