Ambry Genetics | RCV000132210 | SCV000187292 | uncertain significance | Hereditary cancer-predisposing syndrome | 2019-03-17 | criteria provided, single submitter | clinical testing | The p.G972E variant (also known as c.2915G>A), located in coding exon 9 of the BRCA1 gene, results from a G to A substitution at nucleotide position 2915. The glycine at codon 972 is replaced by glutamic acid, an amino acid with similar properties. 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 is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV000814762 | SCV000955187 | uncertain significance | Hereditary breast ovarian cancer syndrome | 2022-08-23 | criteria provided, single submitter | clinical testing | 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. 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. ClinVar contains an entry for this variant (Variation ID: 142793). This variant has not been reported in the literature in individuals affected with BRCA1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 972 of the BRCA1 protein (p.Gly972Glu). |

RCV000132210 | SCV001359689 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-08-30 | criteria provided, single submitter | clinical testing | This missense variant replaces glycine with glutamic acid at codon 972 of the BRCA1 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 observed in an individual affected with breast cancer (PMID: 29905759). 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. |
