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.

Uncertain significance, criteria provided, single submitterclinical testingBaylor GeneticsFeb 22, 2024- -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 25, 2024This sequence change replaces histidine, which is basic and polar, with asparagine, which is neutral and polar, at codon 481 of the BAP1 protein (p.His481Asn). This variant is present in population databases (rs764816701, gnomAD 0.006%). This missense change has been observed in individual(s) with malignant pleural mesothelioma (MPM), which was found in a tumor sample but not confirmed as a germline variant (PMID: 28034829). ClinVar contains an entry for this variant (Variation ID: 472669). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BAP1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Likely benign, criteria provided, single submitterclinical testingMyriad Genetics, Inc.Jul 16, 2024This variant is considered likely benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2022This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
Uncertain significance, criteria provided, single submitterclinical testingColor Diagnostics, LLC DBA Color HealthDec 27, 2022This missense variant replaces histidine with asparagine at codon 481 of the BAP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in a family with individuals affected with cutaneous and uveal melanoma (PMID: 30517737). This variant has been identified in 8/282542 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
