Ambry Genetics RCV000162841 SCV000213328 benign Hereditary cancer-predisposing syndrome 2014-11-19 criteria provided, single submitter clinical testing This alteration is classified as benign based on a combination of the following: 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000160222 SCV000919002 likely benign not specified 2022-12-05 criteria provided, single submitter clinical testing Variant summary: BRCA2 c.4094G>A (p.Cys1365Tyr) results in a non-conservative amino acid change located in the BRCA2 repeat region, between the repeats BRC2 and BRC3 (IPR002093) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 249264 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The variant, c.4094G>A, has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer or other tumor phenotypes, however these reports do not provide unequivocal conclusions about association of the variant with Hereditary Breast and Ovarian Cancer. Co-occurrence with other pathogenic variants have been reported (with BRCA1 c.1175_1214del, p.Leu392_Ser405fs in the BIC database), providing supporting evidence for a benign role. The variant was predicted to be neutral based on tumor pathology, clinical histories, family studies and co-occurrence with deleterious mutations (Lindor 2012) and using a model based co-occurrence in trans with a deleterious mutation, personal and family history of cancer, and analysis of co-segregation with disease (Easton 2007). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven ClinVar submitters including an expert panel have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as enign/likely benign (n=6) and VUS (n=1). Based on the evidence outlined above, the variant was classified as likely benign.
