GeneDx RCV000159867 SCV000209920 benign not specified 2014-10-01 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.
Integrated Genetics/Laboratory Corporation of America RCV000586457 SCV000698829 benign not provided 2016-10-05 criteria provided, single submitter clinical testing Variant summary:The BRCA1 c.1065G>A (p.Lys355Lys) variant causes a synonymous change involving a non-conserved nucleotide with 5/5 splicing algorithms predict no significant effect on splice donor and acceptor sites, which is consistent with an in vitro study (Anczukow et al 2008) showing that the variant did not affect splicing based on a mini-gene assay. This variant was found in 23/121396 control chromosomes, predominantly observed in the European (Non-Finnish) subpopulation at a frequency of 0.0003297 (22/66736). This frequency is lower than the estimated maximal expected allele frequency of a pathogenic BRCA1 variant (0.0010005), but suggests that it may be a rare polymorphism. In at least two reported patients (1 published and 1 unpublished finding from UMD), this variant co-occurred with another deleterious variant in BRCA1, strongly supporting a benign outcome. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, all evidence supports a non-pathogenic nature for the variant, and the variant was classified as benign.

MVZ Praenatalmedizin und Genetik Nuernberg RCV000111537 SCV000777896 likely benign Breast-ovarian cancer, familial 1 2018-05-01 no assertion criteria provided clinical testing This rare variant (gnomAD) was found multiple times in databases to be classified as uncertain or likely benign. Interestingly we found this variant in a patient who harbored also a pathogenic BRCA2-variant (NM_000059.3|c.1813dupA|het). Therefore we rate this variant as likely benign.
