Ambry Genetics	RCV000131683	SCV000186719	likely benign	Hereditary cancer-predisposing syndrome	2019-03-25	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.

Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 251234 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.8573A>G has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer (example, Simard_2007, Spurdle_2008, Shimelis_2017). These data do not allow any conclusion about variant significance. Co-occurrences with pathogenic variants have been reported in the BIC database (BRCA1 c.1054G>T, p.Glu352X; BRCA1 c.2035A>T, p.Lys679X), providing supporting evidence for a benign role. In addition, a multifactorial probability based model utilized for performing systematic assessment of variants of unknown significance in the BRCA genes, which includes analysis of co-occurrence in trans with known deleterious mutations, personal and family history of cancer, tumor pathology and co-segregation with disease in pedigrees, predicts this variant to be likely not pathogenic or of little clinical significance (Lindor_2012). One publication, Hart_2018, reports the HDR activity of this variant to be similar to that of wild-type and classifies the variant as neutral. Seven ClinVar submitters (evaluation after 2014) cite this variant as likely benign (n=4) and as uncertain significance (n=3). Some submitters cite overlapping evidence utilized in the context of this evaluation. Based on the lack of evidence supporting an actionable outcome as outlined above, the variant was classified as benign.
