Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 3P and 3B. PM2PP2BP4_ModerateBS2_Supporting
The NM_004656.4(BAP1):c.1279G>A(p.Gly427Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,816 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G427E) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Dec 05, 2023 | This missense variant replaces glycine with arginine at codon 427 of the BAP1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BAP1-related disorders in the literature. This variant has not been identified 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 30, 2023 | The p.G427R variant (also known as c.1279G>A), located in coding exon 13 of the BAP1 gene, results from a G to A substitution at nucleotide position 1279. The glycine at codon 427 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
BAP1-related tumor predisposition syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 12, 2023 | ClinVar contains an entry for this variant (Variation ID: 489610). This variant has not been reported in the literature in individuals affected with BAP1-related conditions. This variant is not present in population databases (gnomAD no frequency). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt BAP1 protein function. This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 427 of the BAP1 protein (p.Gly427Arg). 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. - |
