Labcorp Genetics (formerly Invitae), Labcorp	RCV000691894	SCV000819692	uncertain significance	Hereditary breast ovarian cancer syndrome	2024-12-02	criteria provided, single submitter	clinical testing	This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 1052 of the BRCA1 protein (p.Asn1052Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 91606). 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 expected to disrupt BRCA1 protein function with a positive 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.
Ambry Genetics	RCV000579719	SCV001180127	uncertain significance	Hereditary cancer-predisposing syndrome	2023-10-02	criteria provided, single submitter	clinical testing	The p.N1052S variant (also known as c.3155A>G), located in coding exon 9 of the BRCA1 gene, results from an A to G substitution at nucleotide position 3155. The asparagine at codon 1052 is replaced by serine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Quest Diagnostics Nichols Institute San Juan Capistrano	RCV003477479	SCV004219339	uncertain significance	not provided	2024-07-24	criteria provided, single submitter	clinical testing	The BRCA1 c.3155A>G (p.Asn1052Ser) variant has been reported in the published literature to be located in a region of the BRCA1 gene that is tolerant to missense sequence changes (PMID: 31911673 (2020)). To the best of our knowledge, this variant has not been reported in individuals with BRCA1-related disorders. The frequency of this variant in the general population, 0.0000066 (1/152126 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant.
