Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA) RCV000495390 SCV000579120 likely benign Breast-ovarian cancer, familial 2 2017-06-29 reviewed by expert panel curation Synonymous substitution variant, with low bioinformatic likelihood to result in a splicing aberration (Splicing prior probability 0.02; http://priors.hci.utah.edu/PRIORS/).
GeneDx RCV000605039 SCV000729674 benign not specified 2015-09-16 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 RCV000588883 SCV000694591 uncertain significance not provided 2016-05-09 criteria provided, single submitter clinical testing Variant summary: The BRCA2 c.2109C>T (p.Thr703Thr) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 1/120736 control chromosomes at a frequency of 0.0000083, which does not exceed the estimated maximal expected allele frequency of a pathogenic BRCA2 variant (0.0007503). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as likely benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as VUS - possibly benign.
