1 Rare CFTR Mutation Cell Collection Protocol (RARE)

Over 1,900 mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein are implicated in causing Cystic Fibrosis (CF). Potential therapies that directly target defective CFTR are being evaluated in important clinical trials, but most target the most common CFTR mutation F508del. Many patients with rare CF mutations are not able to participate in those studies. The RARE study is specifically designed for people with CF caused by rare mutations. Eligible rare mutations are listed below: - CF patients who are homozygous for pre-mature stop codons - CF patients with two mutations in the CFTR gene: i. One allele must be a F508del ii. The other allele must be a pre-mature stop codon mutation - CF patients with two mutations in the CFTR gene: i. At least one allele must be a pre-mature stop codon mutation ii. The second allele can be any of the following: G85E, N1303K, R334W, 3849+10kb C->T, 621+1G->T - CF patients who are homozygous for: G85E, N1303K, R334W, 3849+10kb C->T, or 621+1G->T This is a multi-site, specimen collection study. Investigators will collect blood, intestinal cells and nasal cells from each participant. Cells from these specimens will be used to test future CFTR modulators to see if they might work for people with study eligible rare mutations. Having cells to test in the lab is an important first step in identifying potential new therapies for people with these mutations.
