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.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV001353651	SCV000591371	likely benign	Malignant tumor of breast		no assertion criteria provided	clinical testing	The BRCA1 p.Asn723Asp variant was identified in an individual with hereditary prostate cancer (Zuhlke 2004), and in at least 20 other patients from a data set 55630 patients undergoing clinical BRCA1 mutation screening (Judkins 2005). The variant was also identified in HGMD, LOVD, the BIC database (26X with unknown clinical importance), and UMD (6X as a neutral variant). In UMD the variant was listed once as co-occurring with a known pathogenic mutation in BRCA1 (c.-200_80del (p.Met1SerfsX13)), and Judkins (2005) identified the variant in trans with a different pathogenic BRCA1 mutation (p.Cys64Tyr), increasing the likelihood that the p.Asn723Asp variant does not have clinical importance. This residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. Three in silico studies suggest that the variant is not pathogenic or of no clinical significance (Abkevich 2004, Easton 2007, Lindor 2012). The variant was listed in dbSNP (ID: rs4986845) “With non-pathogenic allele”, with a minor allele frequency of 0.002 (1000 Genomes Project). It was also identified in the NHLBI Exome Sequencing Project with a frequency of 0.007 in African American alleles, and in several HapMap populations including HAPMAP-MKK (frequency: 0.014), HAPMAP-LWK (frequency: 0.011) and HAPMAP-ASW (frequency: 0.01), increasing the likelihood that this is a low frequency benign polymorphism in certain populations of origin. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign.
