GeneDx RCV000045840 SCV000210688 benign not specified 2014-08-07 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.

The observed allele frequency in controls including the large and diverse ExAC cohort is 4/121488(1/30372), which does not exceed the maximal expected alelle frequency for a pathogenic BRCA2 variant (1/1333). However, it has been reported to co-occur with several potentially pathogenic variant in BRCA2 (c.5909C>A, p.Ser1970X - UMD; BRCA2 c.5410_5411delGT (p.Val1804Lysfs) - BIC; BRCA2 c.9382C>T (p.Arg3128Ter) - BIC and BRCA1 IVS3+3A>C (Claes_2003). In addition, multiple reputable databases/clinical diagnostic labs (UMD, GeneDx, and SCRP) and publications (Lindor_2012 and Easton_2007) classify the variant as benign/neutral. Furthermore, functional studies from multiple independent publications report that the variant of interest does not affect splicing (Campos_2003, Claes_2003, Houdayer_2012, and Whiley_2011). Taken together, this BRCA2 intronic variant has been classified as Benign.

Illumina Clinical Services Laboratory,Illumina RCV001110140 SCV001267538 likely benign Fanconi anemia, complementation group D1 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
Illumina Clinical Services Laboratory,Illumina RCV000031826 SCV001267539 likely benign Breast-ovarian cancer, familial 2 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
