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.

BAP1-related tumor predisposition syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Baylor Genetics	Jun 22, 2023	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jan 04, 2024	This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 537 of the BAP1 protein (p.Ser537Gly). This variant is present in population databases (rs747109385, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with BAP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 539898). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glycine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Hereditary cancer-predisposing syndrome

Benign:2

Benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 08, 2023	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. -
