Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BS2_Supporting

The NM_004656.4(BAP1):c.1201_1212delTATGAGGATGAC(p.Tyr401_Asp404del) variant causes a conservative inframe deletion change. The variant allele was found at a frequency of 0.0000235 in 1,614,190 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. Y401Y) has been classified as Likely benign.

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.

The BAP1 c.1201_1212del (p.Tyr401_Asp404del) variant has been reported in the published literature in an individual with features of Cowden/Cowden-like (CS/CS-like) and Bannayan-Riley-Ruvalcaba syndromes (BRRS) (PMID: 29684080 (2018)). The frequency of this variant in the general population, 0.0004 (14/35414 chromosomes in Admixed American subpopulation (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is higher than would generally be expected for pathogenic variants in this gene. Based on the available information, we are unable to determine the clinical significance of this variant. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is causes a 4 amino acid deletion of codons 401 to 404 in exon 12 of the BAP1 protein. To our knowledge, functional studies have not been performed for this variant. This variant has been reported in an individual affected with kidney cancer (PMID: 29684080) and an individual affected with gastrointestinal neuroendocrine neoplasms (PMID: 36653904). This variant has been identified in 17/280226 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The 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. -

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. -

This variant, c.1201_1212del, results in the deletion of 4 amino acid(s) of the BAP1 protein (p.Tyr401_Asp404del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs776606194, gnomAD 0.04%), 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: 412428). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -

The BAP1 c.1201_1212del12 variant is predicted to result in an in-frame deletion (p.Tyr401_Asp404del). This variant has been reported in a kidney renal clear cell carcinoma from The Cancer Genome Atlas (TCGA), as well as a gastrointestinal neuroendocrine neoplasm (Table S9, TCGA ID KIRC_3351-11A Yehia et al. 2018. PubMed ID: 29684080; Table 3, Dai et al. 2023. PubMed ID: 36653904). This variant is reported in 0.040% of alleles in individuals of Latino descent in gnomAD. It is interpreted as uncertain significance by the vast majority of submitters in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/412428/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
