Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals aged 2 and older with a germline mutation in BAP1 or other cancer predisposition genes, as well as their family members.

Probably not a fit

Patients without a germline mutation in BAP1 or other relevant cancer predisposition genes may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to investigate the natural and clinical history of patients with mesothelioma and their family members who have germline mutations in the BAP1 gene and other cancer predisposition genes. Participants, aged 2 and older, will be screened through medical and family history assessments and saliva tests. Those with mesothelioma will be part of the NIH Group, while others can choose to participate in either the NIH Group or a Remote Group, which involves annual phone contact and potential tumor tissue testing. The study seeks to understand how cancer develops in individuals with these genetic mutations.

Why it matters

Potential benefit: If successful, this study could provide insights into cancer development in patients with specific genetic mutations, potentially leading to improved screening and prevention strategies.

How similar studies have gone: Other studies have shown success in understanding the implications of germline mutations in cancer predisposition, making this approach both relevant and potentially impactful.

-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 (or equivalent) confirmed germline mutation in BAP1

OR

--A second degree biological relative with a CLIA (or equivalent) confirmed germline mutation in BAP1 if relevant first degree relative is deceased or unavailable for testing,
