Arm && Interventions
GroupInterventionDescription
tissuetumor specimensThis is a protocol to obtain and/or analyze tumor and germline DNA specimens of patients with MPM, choroidal nevus, and UM.
Primary Outcome Measures
NameTimeMethod
determine the prevalence of germline BAP1 mutations2 years

Prevalence will be estimated as the proportion of all specimens who tested positive for mutation, and reported along with the corresponding exact 95% confidence intervals.

Secondary Outcome Measures
NameTimeMethod
prevalence of somatic BAP1 mutations in disease mesothelioma and metastatic uveal melanoma.2 years

The frequency of somatic mutations will be tabulated by factors of interest such as:

* personal and familial risk factors: age, smoking, and asbestos mesothelioma, personal and family history of cancer or of related diseases (mesothelioma and metastatic uveal melanoma)

* disease characteristics: histology, stage, location, site of metastasis (if present) (for mesothelioma and metastatic uveal melanoma); COMS criteria, GEP class, number of clinical risk factors (for metastatic uveal melanoma)
