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:Uncertain significance

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with melanoma and also in unaffected controls (Gupta 2015, O'Shea 2017); This variant is associated with the following publications: (PMID: 25974357, 28062663, 34426522)

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

In the published literature, this variant has been reported in an individual with uveal melanoma (PMID: 25974357 (2015)) as well as unaffected individuals (PMID: 34426522 (2021), 28062663 (2017)). The frequency of this variant in the general population, 0.000016 (4/250416 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant.

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 574 of the BAP1 protein (p.Ala574Val). This variant is present in population databases (rs761596789, gnomAD 0.003%). This missense change has been observed in individual(s) with uveal melanoma (PMID: 25974357). ClinVar contains an entry for this variant (Variation ID: 412422). 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%. Experimental studies have shown that this missense change does not substantially affect BAP1 function (PMID: 28062663). 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.

Color Diagnostics, LLC DBA Color Health
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This missense variant replaces alanine with valine at codon 574 of the BAP1 protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional assays have not been performed for this variant. This variant has been reported in an individual affected with uveal melanoma (PMID: 25974357) and in a control individual (PMID: 28062663). This variant has also been identified in 4/250416 chromosomes in the general population by the Genome Aggregation Database (gnomAD). 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.

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as 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.
