About this study

To map the gene (or genes) for familial pulmonary fibrosis.

Read the detailed description

BACKGROUND:

Familial pulmonary fibrosis (FPF) is a rare, progressive, life-threatening disease. Although far from definitive, several lines of evidence suggest that it could involve genetic susceptibility and that its expression may be modified gene-environment interactions involving exposure to fibrogenic dusts. If the specific gene loci involved can be identified and their functions characterized, these studies could lead to a better understanding of the etiology of the disease and effective intervention strategies among families at increased risk. It is conceivable that the genetically influenced pathologic mechanisms involved may be shared with other, more common forms of pulmonary fibrosis such as idiopathic pulmonary fibrosis (IPF) or asbestosis. Thus, these studies could lead to the early identification of individuals susceptible to reversible interstitial lung disease and to the development of novel therapeutic approaches.

Familial pulmonary fibrosis is indistinguishable pathologically from idiopathic pulmonary fibrosis and appears to be inherited as an autosomal dominant trait with variable penetrance; pulmonary fibrosis is associated with pleiotropic genetic disorders, such as Hermansky-Pudlak syndrome, neurofibromatosis, tuberous sclerosis, Neimann-Pick disease, Gaucher's disease, and familial hypocalciuric hypercalcemia; pulmonary fibrosis is frequently observed in autoimmune disease, including rheumatoid arthritis and systemic sclerosis; variable susceptibility is evident among workers who are reported to be exposed occupationally to similar concentrations of fibrogenic dusts; and inbred strains of mice differ in their susceptibility to fibrogenic dust.

DESIGN NARRATIVE:

The study uses standard genetic methodology (linkage analysis) to investigate the distribution of polymorphisms for anonymous genetic markers in families with familial pulmonary fibrosis. The comprehensive genome-wide study, using standard genetic markers, will allow identification of loci which subsequently may prove to contain novel genes that play a role in the pathogenesis of pulmonary fibrosis. Once genetic loci are defined in familial pulmonary fibrosis, candidate genes can be identified on the basis of both positional and functional criteria. Moreover, this approach will provide basic information on high priority loci that will be applicable to the rapidly evolving dense human transcript map for pulmonary fibrosis in families with two or more cases of pulmonary fibrosis.

The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

Questions about this trial

What is this clinical trial studying?

An observational study of Pulmonary Fibrosis and Lung Diseases, run by National Heart, Lung, and Blood Institute (NHLBI).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00016627, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2016.
