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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the BAP1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 14 curated pathogenic missense variants (we use a threshold of 10). The gene has 16 curated benign missense variants. Gene score misZ: 2.6442 (below the threshold of 3.09). Trascript score misZ: 3.2667 (above the threshold of 3.09). GenCC associations: The gene is linked to BAP1-related tumor predisposition syndrome, Kury-Isidor syndrome, renal cell carcinoma.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.784

Collection Method: clinical testing

The p.W196L variant (also known as c.587G>T), located in coding exon 8 of the BAP1 gene, results from a G to T substitution at nucleotide position 587. The tryptophan at codon 196 is replaced by leucine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
