Ambry Genetics	RCV000162531	SCV000212930	benign	Hereditary cancer-predisposing syndrome	2014-11-18	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 Laboratory Services, Illumina	RCV000111799	SCV000403076	benign	Breast-ovarian cancer, familial, susceptibility to, 1	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 benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV000496808	SCV000591239	benign	not specified		no assertion criteria provided	clinical testing	The BRCA1 p.Lys38= variant was identified in 16 of 604 proband chromosomes (frequency: 0.026) from Asian and Colombian individuals or families with hereditary breast and/or ovarian cancer or early-onset breast cancer and was present in 3 of 142 control chromosomes (frequency: 0.021) from healthy individuals (Torres_2007_17080309, Ho_2000_10951344, Chen_2003_12602912, Song_2006_16835750, Toh_2008_18431501). The variant was also identified in dbSNP (ID: rs1800062) as “With Uncertain significance, other allele”, ClinVar and Clinvitae (11x classified as benign by ENIGMA, Laboratory Corporation of America, Baylor Miraca Genetics, British Columbia Cancer Agency (COGR), Sinai Health System (COGR), ARUP Laboratories, Invitae, Counsyl, Ambry Genetics, SCRP, BIC; 2x classified as likely benign by Illumina Clinical Services and CHEO), GeneInsight-COGR (classified as likely benign/benign by COGR consensus and Sinai Health System), LOVD 3.0 (11 entries, classified as does not affect function or not classified), UMD-LSDB (37 entries, 2 of which have co-occurring pathogenic variants), BIC Database (18 entries, classified as not pathogenic), and the Zhejiang Colon Cancer Database (5 entries classified as no known pathogenicity). The variant was not identified in the COSMIC, MutDB, or ARUP Laboratories databases. The variant was identified in control databases in 1135 of 276592 chromosomes (18 homozygous) at a frequency of 0.004 increasing the likelihood this could be a low frequency variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 4 of 23984 chromosomes (freq: 0.0002), Other in 13 of 6450 chromosomes (freq: 0.002), Latino in 368 of 34346 chromosomes (freq: 0.01), European Non-Finnish in 2 of 126380 chromosomes (freq: 0.00002), East Asian in 741 of 18846 chromosomes (freq: 0.04), European Finnish in 1 of 25776 chromosomes (freq: 0.00004), and South Asian in 6 of 30688 chromosomes (freq: 0.0002) while the variant was not observed in the Ashkenazi Jewish population. The p.Lys38= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence and 2 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign.
