Genes affected

BAP1 (HGNC:950): (BRCA1 associated protein 1) This gene belongs to the ubiquitin C-terminal hydrolase subfamily of deubiquitinating enzymes that are involved in the removal of ubiquitin from proteins. The encoded enzyme binds to the breast cancer type 1 susceptibility protein (BRCA1) via the RING finger domain of the latter and acts as a tumor suppressor. In addition, the enzyme may be involved in regulation of transcription, regulation of cell cycle and growth, response to DNA damage and chromatin dynamics. Germline mutations in this gene may be associated with tumor predisposition syndrome (TPDS), which involves increased risk of cancers including malignant mesothelioma, uveal melanoma and cutaneous melanoma.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg385*) in the BAP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BAP1 are known to be pathogenic (PMID: 21874000, 23684012). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with mesothelioma, cutaneous melanoma and/or uveal melanoma (PMID: 22545102, 25974357, 27181379). ClinVar contains an entry for this variant (Variation ID: 485271). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R385* pathogenic mutation (also known as c.1153C>T), located in coding exon 12 of the BAP1 gene, results from a C to T substitution at nucleotide position 1153. This changes the amino acid from an arginine to a stop codon within coding exon 12. This mutation has been shown to segregate with disease in a family with several BAP1-associated tumors including cutaneous melanoma, ocular melanoma, and atypical melanocytic nevi (Njauw CN et al. PLoS ONE. 2012;7(4):e35295). The p.R385* mutation has also been reported in an individual diagnosed with a meningioma, multiple cutaneous melanomas, as well as meosothelioma (Betti M et al. Cancer Lett. 2016 08;378:120-30). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
