GeneDx	RCV000440462	SCV000518131	likely benign	not specified	2017-08-15	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	RCV000440462	SCV000694707	likely benign	not specified	2018-10-01	criteria provided, single submitter	clinical testing	Variant summary: BRCA2 c.3581G>A (p.Gly1194Asp) results in a non-conservative amino acid change located in the BRCA2 repeat region. 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 8.3e-05 in 278020 control chromosomes (gnomAD). This frequency is not higher than expected for a pathogenic variant in BRCA2 causing Hereditary Breast and Ovarian Cancer (8.3e-05 vs 0.00075), allowing no conclusion about variant significance. The variant, c.3581G>A, has been reported in the literature in individuals affected with Breast and Ovarian Cancer (e.g. Alsop 2012, Musolino 2007), without strong evidence for pathogenicity. The variant was predicted to be neutral with a multifactorial probability model, based on tumor pathology, clinical histories, family studies and co-occurrence with deleterious mutations (Easton 2007). In addition, UMD BRCA2 database classified this variant as 'likely neutral'. Six 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 (3x) / likely benign (3x). Based on the evidence outlined above, the variant was classified as likely benign.

Illumina Clinical Services Laboratory,Illumina	RCV001111917	SCV001269525	uncertain significance	Fanconi anemia, complementation group D1	2019-05-20	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 did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina	RCV000077309	SCV001269526	uncertain significance	Breast-ovarian cancer, familial 2	2019-05-20	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. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
