GeneDx	RCV000120366	SCV000210674	benign	not specified	2016-09-16	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	RCV000162603	SCV000213027	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.

Illumina Clinical Services Laboratory,Illumina	RCV000114008	SCV000383794	likely benign	Breast-ovarian cancer, familial 2	2018-03-06	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine	RCV000120366	SCV000605776	uncertain significance	not specified	2016-12-21	criteria provided, single submitter	clinical testing	Variant classified as Uncertain Significance - Favor Benign. The p.Lys2950Asn va riant in BRCA2 has been reported in at least 1 individual with BRCA2-associated cancer (Blay 2013). This variant has also been identified in 0.2% (21/11524) of Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadi nstitute.org; dbSNP rs28897754). Computational prediction tools and conservation analysis suggest that the p.Lys2950Asn variant may impact the protein, though t his information is not predictive enough to determine pathogenicity. In summary, while the clinical significance of the p.Lys2950Asn variant is uncertain, its f requency suggests that it is more likely to be benign.

Illumina Clinical Services Laboratory,Illumina	RCV001112820	SCV001270519	uncertain significance	Fanconi anemia, complementation group D1	2018-03-06	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
