Ambry Genetics RCV000166150 SCV000216922 uncertain significance Hereditary cancer-predisposing syndrome 2024-09-16 criteria provided, single submitter clinical testing The p.S282L variant (also known as c.845C>T), located in coding exon 9 of the BRCA1 gene, results from a C to T substitution at nucleotide position 845. The serine at codon 282 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV000824141 SCV000965027 uncertain significance Hereditary breast ovarian cancer syndrome 2023-11-24 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 282 of the BRCA1 protein (p.Ser282Leu). 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: 186539). 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 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.
