Ambry Genetics RCV002337790 SCV002640091 uncertain significance Hereditary cancer-predisposing syndrome 2022-05-24 criteria provided, single submitter clinical testing The p.N1596S variant (also known as c.4787A>G), located in coding exon 10 of the BRCA2 gene, results from an A to G substitution at nucleotide position 4787. The asparagine at codon 1596 is replaced by serine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. 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.
University of Washington Department of Laboratory Medicine, University of Washington RCV002337790 SCV003852095 likely benign Hereditary cancer-predisposing syndrome 2023-03-23 criteria provided, single submitter curation Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673).
Color Diagnostics, LLC DBA Color Health RCV002337790 SCV004362081 uncertain significance Hereditary cancer-predisposing syndrome 2023-11-07 criteria provided, single submitter clinical testing This missense variant replaces asparagine with serine at codon 1596 of the BRCA2 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 been reported in an individual affected with breast cancer (PMID: 16616110). 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.
