Cystic fibrosis (CF) is a recessive genetic disorder caused by mutations in CF transmembrane conductance regulator (CFTR) gene. CF has multi-organ involvement, but respiratory disease is the major cause of morbidity and mortality. The median age of survival in CF is only 37 years, but there is a broad range of disease severity in the lung, even among patients with identical CFTR genotypes, including ΔF508 homozygotes.
This project holds great promise for defining a robust molecular phenotype for CF lung disease, which relates to prognosis, and new targets for therapy. By using a large and well-defined population of ΔF508 homozygotes who also have whole genome SNP data, and by studying gene expression across the whole transcriptome in a large number of samples of two relevant tissues (respiratory epithelium and transformed lymphocytes), we will be uniquely positioned to develop an integrated view of molecular mechanisms underlying CF lung disease severity.
