This study is taking place at multiple care centers across the U.S. Researchers will collect and make available for study cells from people with rare CFTR mutations.
This study will consist of a single visit where researchers will collect nasal cells and a blood sample. CFTR genotype will be confirmed and a repository of rare CFTR mutation specimens will be established and made available to other researchers for further study.
This study is for people with CF over the age of 2 who have a rare CFTR mutation. This study may require nasal swabs and/or other methods of cell collection.
