Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4BP6
The NM_000059.4(BRCA2):c.3482A>G(p.Asp1161Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,990 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D1161N) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 31, 2023 | The p.D1161G variant (also known as c.3482A>G), located in coding exon 10 of the BRCA2 gene, results from an A to G substitution at nucleotide position 3482. The aspartic acid at codon 1161 is replaced by glycine, an amino acid with similar properties. 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 of this alteration remains unclear. - |
Likely benign, criteria provided, single submitter | curation | University of Washington Department of Laboratory Medicine, University of Washington | Mar 23, 2023 | Missense variant in a coldspot region where missense variants are very unlikely to be pathogenic (PMID:31911673). - |

Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jan 08, 2024 | Variant summary: BRCA2 c.3482A>G (p.Asp1161Gly) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 250870 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3482A>G has been reported in the literature in at least one individual affected with esophageal squamous cell carcinoma (e.g., Ko_2020). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication was ascertained in the context of this evaluation (PMID: 31396961). ClinVar contains an entry for this variant (Variation ID: 409539). Based on the evidence outlined above, the variant was classified as uncertain significance. - |
