Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) RCV000411196 SCV000578523 likely benign Breast-ovarian cancer, familial, susceptibility to, 2 2017-06-29 reviewed by expert panel curation Synonymous substitution variant, with low bioinformatic likelihood to result in a splicing aberration (Splicing prior probability 0.02; http://priors.hci.utah.edu/PRIORS/).
GeneDx RCV000160258 SCV000210693 benign not specified 2014-06-20 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.
Ambry Genetics RCV000163339 SCV000213873 likely benign Hereditary cancer-predisposing syndrome 2015-01-14 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000586788 SCV000695274 likely benign not provided 2017-02-13 criteria provided, single submitter clinical testing Variant summary: The BRCA2 c.9837A>G (p.Leu3279Leu) variant causes a synonymous change involving the alteration of a non-conserved nucleotide, which 5/5 splice prediction tools predict no significant impact on normal splicing and ESE finder predicts that this variant may create an ESE binding site for SC35. However, these predictions have yet to be confirmed by functional studies. The variant of interest has not been observed in controls (ExAC, 1000 Gs, or ESP), nor has it been reported, to our knowledge, in affected individuals via publications. However, an internal LCA sample reports the variant to co-occur with a likely pathogenic BRCA1 variant, c.3964A>T (p.Lys1322X). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign/likely benign. Taken together, this variant is classified as "Likely Benign."
