GeneDx	RCV000123888	SCV000167233	benign	not specified	2013-12-30	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.

This variant is located at a position that is not widely known to affect splicing, 3/5 splicing prediction programs via Alamut predict no significant effect on splicing, and mutation taster predicts the variant to be a polymorphism. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.012%, predominantly observed in the East Asian subpopulation at a frequency of 0.18%. This frequency exceeds the maximal expected allele frequency for a pathogenic variant in BRCA1 (0.10%), suggesting this is a benign polymorphism found primarily in population(s) of East Asian origin. The variant has been reported in multiple databases to co-occur in individuals with pathogenic BRCA1 variants including two patients with c.2296_2297delAG, p.Ser766X (UMD), one patient with c.68_69delAG, p.Glu23ValfsX17 (UMD), and one patient with c.188T>A, p.Leu63Ter (BIC). Taken together, the multiple co-occurrences with pathogenic variants along with the intronic nature of the variant and the relatively high frequency in the East Asian population, this variant was classified as Benign.

Illumina Laboratory Services, Illumina	RCV000112769	SCV001284087	uncertain significance	Breast-ovarian cancer, familial, susceptibility to, 1	2017-05-04	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
