Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP2

The NM_004656.4(BAP1):​c.1427T>A​(p.Val476Glu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V476A) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: BAP1 NM_004656.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 6.63

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

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BAP1. . Gene score misZ 2.6442 (greater than the threshold 3.09). Trascript score misZ 3.2667 (greater than threshold 3.09). GenCC has associacion of gene with BAP1-related tumor predisposition syndrome, Kury-Isidor syndrome, renal cell carcinoma.
