Ambry Genetics | RCV000218484 | SCV000278162 | uncertain significance | Hereditary cancer-predisposing syndrome | 2015-09-04 | criteria provided, single submitter | clinical testing | The p.S1674T variant (also known as c.5021G>C), located in coding exon 10 of the BRCA2 gene, results from a G to C substitution at nucleotide position 5021. The serine at codon 1674 is replaced by threonine, an amino acid with 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. In the ESP, this variant was not observed in 6477 samples (12954 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 150000 alleles tested) in our clinical cohort. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence for this variant is limited at this time, the clinical significance of p.S1674T remains unclear |

RCV000816027 | SCV000956515 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2025-01-28 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 1674 of the BRCA2 protein (p.Ser1674Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with BRCA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 233728). 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 BRCA2 protein function with a negative predictive value of 95%. 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. |
