Research Focus

Only a subset of cystic fibrosis (CF) patients develop severe liver disease (biliary cirrhosis with portal hypertension; CFLD), and thisdoes not correlate with the type of CF gene (CFTR) mutation. Thus, there must be other (non-CFTR) genetic variation that contributes to the development of CFLD. The goals of our research are to study candidate genes that might modify CF liver disease, analyze genome-wide association study (GWAS) of 570,000 genetic markers (SNPs) in patients with CFLD, enroll additional patients with CFLD, and perform another GWAS in additional patients with CFLD. The long term goal of our research is to identify the major gene modifiers for CFLD, which will provide the opportunity for a novel, genetic-based technique to identify CF children at risk for CFLD. If successful, our study will provide novel prognostic approaches, and identification of novel, targeted therapies to prevent severe biliary cirrhosis before it occurs in CF children.
