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. 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....
