Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate inherited genetic factors that play a role in the development of familial pulmonary fibrosis and to identify a group of genes that predispose individuals to develop pulmonary fibrosis. Finding the genes that cause pulmonary fibrosis is the first step at developing better methods for early diagnosis and improved treatment for pulmonary fibrosis. The overall hypothesis is that inherited genetic factors predispose individuals to develop pulmonary fibrosis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Familial Pulmonary Fibrosis (FPF) is a sub-category of the idiopathic interstitial pneumonias (IIPs). IIPs are progressive lung conditions, with limited treatment options and unknown etiology. Though the IIPs have been associated with both genetic risk factors and environmental exposures, the molecular mechanism underlying disease progression remain poorly understood. This investigation seeks to identify a group of genetic loci that play a role in the development of familial interstitial pneumonia (FIP) or FPF, where 2 or more cases of IIP are seen within a family.

Exclusion Criteria

* Individuals whose pulmonary fibrosis is due to a known cause rather than idiopathic
* Individuals whose pulmonary fibrosis is due to a broader genetic syndrome
