ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000034424 SCV000883505 likely benign not provided 2018-04-24 criteria provided, single submitter clinical testing The BRCA2 c.10111A>G; p.Thr3371Ala variant (rs80358393) has been described in individuals affected with breast cancer who also harbor a known pathogenic BRCA1 variant (see link to BIC database). This variant has also been observed in individuals with no personal or family history of cancer (Johnston 2012). It is reported in ClinVar (Variation ID: 37720) and observed in the general population at an overall frequency of 0.0007% (2/277018 alleles) in the Genome Aggregation Database. The threonine at codon 3371 is moderately conserved but computational algorithms (PolyPhen-2, SIFT) predict this variant to be tolerated. Based on available information, this variant is considered likely benign. References: BIC database: https://research.nhgri.nih.gov/bic/ Johnston J et al.

GeneDx RCV000043714 SCV000210697 likely benign not specified 2017-09-06 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Integrated Genetics/Laboratory Corporation of America RCV000034424 SCV000694494 likely benign not provided 2016-08-22 criteria provided, single submitter clinical testing Variant summary: Variant affects a non-conserved nucleotide and results in a replacement of a medium size and polar Threonine (T) with a small size and hydrophobic Alanine (A). The affected Threonine (aa 3371) is located at the C-terminal end of the 3410 amino acid long protein, outside of the know BRCA2 functional domains. 3/4 in silico tools predict neutral outcome for this change (SNPs&GO was not considered due to low reliability index). The variant is absent from the large and broad cohorts of the ExAC project. It was reported in HBOC spectrum patients however without strong evidence for pathogenicity. Additionally, BIC database lists two patients with co-occurrence with a potentially pathogenic BRCA1 mutations p.Gln1538Ter and p.Leu1260?fs indicating the variant to be in the benign spectrum. One internal sample also carried a pathogenic BRCA1 variant c.5335delC/p.Q1779fs*14, further supporting the benign classification. Furthermore, clinical diagnostic centers classify variant as Likely Benign/Benign (without evidence to independently evaluate). Considering all evidence, the variant is classified as Likely Benign until more information becomes available.
