This test is a full gene sequencing of the BAP1 gene intended for germline testing of patients and family members suspected of having BAP1 Tumor Predisposition Syndrome, which is inherited in autosomal dominant manner. Somatic testing on tumor tissue (or other tissues) is NOT performed by this testing.

Individuals who have a pathogenic variant (mutation) in the BAP1 gene?are predisposed to the development of melanocytic skin lesions, melanomas, and mesotheliomas. While the specific spectrum and frequency of tumor associated with germline BAP1 mutations is currently not known, there are common tumor types described in the cases reported in the literature. Most frequently, BAP1 mutations have been associated with epithelioid melanocytic tumors and melanomas. Multiple individuals have been described with mesotheliomas including both peritoneal and pleural tumors. Melanomas associated with BAP1 mutations are typically cutaneous or uveal.
