Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BS2_Supporting
The NM_004656.4(BAP1):c.1445C>T(p.Ser482Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000479 in 1,461,724 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S482W) has been classified as Uncertain significance.

BAP1-related tumor predisposition syndrome    Uncertain:2 
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 482 of the BAP1 protein (p.Ser482Leu). This variant is present in population databases (rs753329341, gnomAD 0.0009%). This missense change has been observed in individual(s) with uveal melanoma (PMID: 25974357). ClinVar contains an entry for this variant (Variation ID: 485301). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt BAP1 protein function with a negative predictive value of 80%. 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    Uncertain:1Benign:1 
This missense variant replaces serine with leucine at codon 482 of the BAP1 protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with uveal melanoma (PMID: 25974357). This variant has been identified in 1/251142 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 likely 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. -
