Ambry Genetics RCV000130660 SCV000185546 uncertain significance Hereditary cancer-predisposing syndrome 2014-01-28 criteria provided, single submitter clinical testing The p.N243D variant (also known as c.727A>G or 846A>G) is located in coding exon 9 of the BRCA1 gene. This alteration results from an A to G substitution at nucleotide position 727. The asparagine at codon 243 is replaced by aspartic acid, an amino acid with highly similar properties.This variant was not reported in population-based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP) and 1000 Genomes Project.Based on protein sequence alignment, 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 ofp.N243Dremains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV002514733 SCV003014735 uncertain significance Hereditary breast ovarian cancer syndrome 2022-04-19 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 243 of the BRCA1 protein (p.Asn243Asp). 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: 141938). 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 BRCA1 protein function. 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.
