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.

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 26, 2023	This sequence change creates a premature translational stop signal (p.Lys453Argfs*15) in the BAP1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BAP1 are known to be pathogenic (PMID: 21874000, 23684012). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 434478). For these reasons, this variant has been classified as Pathogenic. -

The c.1358_1359delAA pathogenic mutation, located in coding exon 13 of the BAP1 gene, results from a deletion of two nucleotides at nucleotide positions 1358 to 1359, causing a translational frameshift with a predicted alternate stop codon (p.K453Rfs*15). This alteration was detected in an individual with uveal melanoma (Huang KL et al. Cell, 2018 04;173:355-370.e14) and has also been observed in an individual with breast cancer (Hong JH et al. NPJ Genom Med, 2020 Nov;5:50). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
