An observational study of Familial Cancer and BRCA1-Associated Protein-1 (BAP1) Mutations, run by National Cancer Institute (NCI) at 1 site in United States.
Trial summary
Background: A germline mutation is a change to a person s genes that is carried through their DNA. These mutations can be passed on from parents to their offspring. Germline mutations in a gene called BAP1 are linked to the development of mesothelioma and other cancers. Read more about this study

About this study
Background:
A germline mutation is a change to a person s genes that is carried through their DNA. These mutations can be passed on from parents to their offspring. Germline mutations in a gene called BAP1 are linked to the development of mesothelioma and other cancers. Researchers want to follow people with these mutations to learn more.

Objective:
To see if researchers can improve how people who have or are suspected to have a BAP1 mutation are monitored over time.
Eligibility:
People age 30 and older who are suspected to have a BAP1 germline mutation.
Design:
Participants will be screened with a personal and family medical history. Their medical records may be reviewed. They will give a blood or saliva sample to test for a BAP1 mutation. They will get genetic counseling.
To take part in this study, participants will enroll on 2 to 3 other protocols.
Participants will have a physical exam. They may have a tumor biopsy. They will give blood and urine samples. They will have skin and eye exams.
Some participants will have video-assisted thoracoscopy to examine the chest and lungs and diagnose suspicious areas. For this, a small camera is inserted into the chest through a small incision.
Some participants will have laparoscopy to examine the organs inside the abdomen. For this, a small camera is inserted into the abdomen through a small incision.
Participants will have imaging scans of the chest, abdomen, and pelvis. They may have brain scans.
Participants will visit the NIH once a year for follow-up exams.
Participation lasts indefinitely.
Read the detailed description
Background:
- Mutations involving BRCA1-Associated Protein-1 (BAP1), a nuclear deubiquitinase involved in epigenetic regulation of gene expression, DNA repair, and cellular energetics, have emerged as one of the most common somatic mutations in malignant mesotheliomas.
- Germline mutations involving BAP1 predispose individuals to mesothelioma as well as a variety of other malignancies including melanoma and lung, renal, gastric, breast, and biliary tract cancers.
- The cancer penetrance of germline BAP1 mutations is nearly 100%, with most patients developing multiple neoplasms.
- Presently there are no established guidelines for surveillance of cancer patients with germline BAP1 mutations or of cancer-free individuals with germline BAP1 mutations.
Objectives:
To prospectively gather information related to the use of dual energy computed tomographic imaging (DECT) together with minimally invasive surgical surveillance for early detection of pleural or peritoneal mesothelioma in participants with BAP1 tumor predisposition syndrome (TPDS)
Eligibility:
- Individuals with a history of any malignancy with known or suspected germline mutation involving BAP1.
- First- or second-degree relatives of patients with documented germline BAP1 mutations, who are also found to carry similar germline mutations.
- Age >= 30
Design:
- Participants with suspected hereditary tumor predisposition syndromes will undergo germline evaluation using CLIA-certified next-gen sequencing (NGS).
- First- and second-degree relatives of patients with germline BAP1 mutations who become protocol participants will be offered similar NGS evaluation.
- Participants with germline mutations in BAP1 will undergo periodic dual energy CT (DECT) scans of the chest, abdomen, and pelvis. Plasma cell-free DNA (cfDNA) will be assessed at similar intervals, and minimally invasive surveillance procedures (i.e., video-assisted thoracoscopy and laparoscopy) will be performed periodically to detect early, subclinical malignancies that may be amenable to potentially curative local interventions.

What is this clinical trial studying?
An observational study of Familial Cancer and BRCA1-Associated Protein-1 (BAP1) Mutations, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 0 exclusion criteria. 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: looking for participants now, as of the sponsor's last update on 29 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rebecca B Alexander ((240) 781-4037, rebecca.alexander@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prospectively gather information related to the use of dual energy computed tomographic imaging (DECT) together with minimally invasive surveillance for early detection of mesotheliomas in patients with BAP1 TPDS (time frame: annual or biennial follow-up, 5 years interim analysis). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04431024, which also lists 1 linked publication.
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 29 Oct 2026.
