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.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV000111927	SCV000591408	benign	Breast-ovarian cancer, familial, susceptibility to, 1		no assertion criteria provided	clinical testing	The p.Gly911Gly variant has been identified in 12 out of 8424 proband chromosomes (frequency 0.001) in individuals with sporadic and familial breast and ovarian cancer phenotype; and was absent in 48 control chromosomes included in these studies (Judkins 2005, van der Hout 2006, Uhrhammer 2008, Caux-Moncoutier 2009, Borg 2010). It is listed in dbSNP database” (ID#: rs1800740) while no information was provided, however, in the exome server it is found in 5/8595 (frequency 0.0006) in European and 1/4405 (frequency 0.0003) in African populations, suggesting that this is a benign variant. In addition, in the UMD database, this variant has been identified in 2 (out of 43) individuals with breast or ovarian cancers, where a second pathogenic BRCA1 or BRCA2 mutation was also detected, further suggesting that this is a benign variant. In addition, it was identified by our laboratory in one individual with a second pathogenic variant. This variant is not expected to have clinical significance because it does not alter an amino acid residue, is not located near a splice junction. In addition, in-silico or computational prediction software (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predicts no change in the splice site prediction score. In summary, based on above information this variant is classified as Benign
