Summary

This study examines "modifier genes" that may play a role in the development of CF liver disease. Modifier genes are genes, other than the CF gene (CFTR), which may directly or indirectly have an affect on how the body responds to the conditions that develop as the result of the defective CFTR gene. Scientists have wondered why some patients with CF develop CF liver disease and why some patients with CF do not. To better understand the problem, this study was designed to examine the genetic makeup of CF patients who are considered to have severe liver disease to see if they can identify any modifier genes. Researchers will study blood samples, pulmonary function tests, and other medical information in hopes that a connection can be made between genetic make-up and how severe the liver disease is. The identification of modifier genes that influence disease severity may ultimately lead to a better understanding of CF liver disease, and may be useful in the development of new treatments.
