NM_032043.3:c.2582C>G
Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP3_Moderate
The NM_032043.3(BRIP1):c.2582C>G(p.Ser861Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000434 in 1,613,880 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S861P) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
This missense variant replaces serine with cysteine at codon 861 of the BRIP1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast cancer and melanoma (PMID: 26921362, 30414346). This variant has been identified in 4/281246 chromosomes 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. -
The p.S861C variant (also known as c.2582C>G), located in coding exon 18 of the BRIP1 gene, results from a C to G substitution at nucleotide position 2582. The serine at codon 861 is replaced by cysteine, an amino acid with dissimilar properties. This variant has been reported in breast cancer and melanoma cohorts (Easton DF et al. J Med Genet, 2016 05;53:298-309; Potjer TP et al. Int J Cancer, 2019 05;144:2453-2464). This variant was identified in1 of 1528 breast cancer cases and 0 of 3733 unaffected controls (Dumont M et al. Cancers (Basel), 2022 Jul;14:). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
Familial cancer of breast;C1836860:Fanconi anemia complementation group J Uncertain:1
This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 861 of the BRIP1 protein (p.Ser861Cys). This variant is present in population databases (rs774415723, gnomAD 0.003%). This missense change has been observed in individual(s) with personal and/or family history of breast cancer or melanoma (PMID: 26921362, 30414346). ClinVar contains an entry for this variant (Variation ID: 187562). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on BRIP1 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. -
