GeneDx RCV000160222 SCV000210602 likely benign not specified 2017-06-23 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 RCV000160222 SCV000919002 likely benign not specified 2018-09-25 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), i.e. not affecting a known functional domain. 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 3.3e-05 in 244272 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_Ser405?fs 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. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as Likely Benign.
