Background:
-A gene provides instructions to the body. Mutated genes can sometimes cause cancer. Germline mutations are those people are born with. These mutations in the BAP1 gene can cause mesothelioma and other cancers. Researchers want to study people with germline mutations of BAP1 and other genes known to cause cancer.
Objective:
-To learn how cancer might develop in people with certain gene mutations.
Eligibility:
-People ages 2 and older with a germline mutation in BAP1 or another gene that might cause cancer
Design:
-
Participants will be screened with:
- Medical and family history
- Saliva test
- Participants with mesothelioma will be in the NIH Group. Participants without mesothelioma can choose to be in either the NIH Group or the Remote Group.
- Remote Group participants will have a medical and family history by phone. If they have tumor tissue from a previous surgery, it will be tested. They will be contacted once a year by phone.
-
NIH Group participants will have a baseline visit. This can take up to 4 days. They may have to stay in the area overnight. The visit will include:
- Physical exam
- Evaluation of tumor tissue if available
- Optional tumor biopsy
- Blood tests
- Scans: A machine will take pictures of the body.
- Photographs of skin lesions or other issues
- Skin exam
- Eye exam
- NIH Group participants will have visits once or twice a year. These will include a physical exam, lab tests, scans, and other tests as needed.
- Participants who have a confirmed mutation will be asked to contact any relatives who may be at risk and ask them about joining the study.

1/Germline positive mesothelioma
Individuals with mesothelioma who have a BAP1 or other DNA repair/cancer predisposition mutation regardless of CLIA confirmation

- Incidence and frequencies of Cancers [ Time Frame: ongoing ]Standard exploratory and descriptive measures will be used. Counts, incidence, and frequencies of cancers identified via screening procedures on this trial will be reported, all in the context of an exploratory study with appropriate caveats.

- Inclusion Criteria:
Inclusion Criteria for Genetic Testing:
Cohort 1:
- Subject with pathology confirming a diagnosis of mesothelioma.
- Subject must have a deleterious germline BAP1 mutation. Results from either research or clinical analyses are sufficient for this criterion.
OR
-Subject with mesothelioma otherwise eligible for genetic testing in Cohort 2
OR
- Subject must have deleterious germline mutation in another DNA repair/cancer predisposition gene(s) that is listed on a commercially available, cancer-associated common or customized gene panel. Results from either research or clinical analyses are sufficient for this criterion.
- Age greater than or equal to 2 years
Cohort 2:
-Individual with a germline BAP1 mutation who does not have a history of mesothelioma (other cancers are allowed). Results from either research or clinical analyses are sufficient for this criterion.
OR
-Individual with no history of mesothelioma with:
--A biological first degree relative (living or deceased) with a history of mesothelioma
OR
--A first degree biological relative with a CLIA confirmed germline mutation in BAP1
OR
--A second degree biological relative with a CLIA confirmed germline mutation in BAP1 if relevant first degree relative is deceased or unavailable for testing,
OR
--A first degree biological relative with mesothelioma and a CLIA confirmed germline mutation in another DNA-repair/cancer predisposition gene that is listed on a commercially available, cancer-associated common or customized gene panel
OR
-
A second degree biological relative with mesothelioma and a CLIA confirmed germline mutation in BAP1
-Age:
- greater than or equal to 2 years for subjects with a BAP1 or TP53 mutation or with a first degree relative relative that has a germline mutation in TP53 or BAP1
- greater than or equal to 16 years for all other eligible potential mutations
All participants must understand and be willing to sign a written informed consent
Exclusion Criteria for Genetic Testing
None
Inclusion Criteria for Surveillance:
- Genetic testing criteria including age restrictions for respective cohorts must be met
- Subjects in Cohort 1 may be enrolled with positive results for germline BAP1 mutation or another DNA repair/cancer predisposition gene(s) that is listed on a commercially available, cancer-associated common or customized gene panel regardless of CLIA confirmation
- Subjects in Cohort 2 must have CLIA confirmed germline BAP1 mutation or another DNA repair/cancer predisposition gene(s) that is listed on a commercially available, cancer-associated common or customized gene panel
Exclusion Criteria for Surveillance:
None
