Ambry Genetics	RCV000217504	SCV000272958	likely benign	Hereditary cancer-predisposing syndrome	2019-01-07	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
Color Diagnostics, LLC DBA Color Health	RCV000217504	SCV000683483	uncertain significance	Hereditary cancer-predisposing syndrome	2023-01-27	criteria provided, single submitter	clinical testing	This missense variant replaces phenylalanine with isoleucine at codon 81 of the BRCA2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). In a functional study, this variant showed 72% homology-directed repair capacity of wild-type BRCA2 (PMID: 35979650). This variant has been detected in a breast cancer case-control meta-analysis in 6/60463 cases and 2/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID BRCA2_001289) and also in an individual affected with prostate cancer (PMID: 21952622). This variant also has been reported in 1 individual age 70 years or older without cancer in the FLOSSIES database and in 6/251364 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.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV002295275	SCV000694607	uncertain significance	not specified	2022-09-12	criteria provided, single submitter	clinical testing	Variant summary: BRCA2 c.241T>A (p.Phe81Ile) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 251364 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.241T>A has been reported in the literature in individuals affected with various cancers, including prostate cancer (Kote-Jarai_2011, Johansson_2019), breast cancer (Dorling_2021) and cutaneous melanoma (Johansson_2019). The variant was also found at a carrier frequency of 0.0001365 in European American women over the age of 70 without history of cancer (FLOSSIES database). These reports 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, and a minigene splicing assay demonstrated that the variant had no impact splicing (Tubeuf_2020). Seven ClinVar submitters have assessed the variant since 2014: five classified the variant as uncertain significance and two as likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance.

Quest Diagnostics Nichols Institute San Juan Capistrano	RCV000586268	SCV004219539	uncertain significance	not provided	2024-03-21	criteria provided, single submitter	clinical testing	The BRCA2 c.241T>A (p.Phe81Ile) variant has been reported in individuals with prostate cancer (PMID: 21952622 (2011)) and melanoma (PMID: 31464824 (2019)). It has also been reported in individuals with breast cancer as well as in reportedly healthy individuals in a breast cancer association study (PMID: 33471991 (2021), see also LOVD (http://databases.lovd.nl/shared/genes/BRCA2)). The frequency of this variant in the general population, 0.000053 (6/113686 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant.
