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.

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 315 of the BAP1 protein (p.Glu315Ala). This variant is present in population databases (rs149974450, gnomAD 0.02%). This missense change has been observed in individual(s) with renal cell carcinoma and malignant pleural mesothelioma (PMID: 28687356, 31034483). ClinVar contains an entry for this variant (Variation ID: 412406). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The BAP1 c.944A>C (p.Glu315Ala)missense change has a maximum subpopulation frequency of 0.016% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/3-52439298-T-G?dataset=gnomad_r2_1). Five of seven in silico tools predict a benign effect of this variant on protein function (BP4), but these predictions have not been confirmed by functional studies. This variant has been reported in individuals with renal cell carcinoma, malignant mesothelioma, and pediatric osteosarcoma (PMID: 31034483, 28687356, 26580448). It is present 2X in a database of women older than 70 years of age who have never had cancer (https://whi.color.com/variant/3-52439298-T-G). In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: BP4.

Ambry Genetics

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This 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.
