GeneDx RCV000236275 SCV000293480 uncertain significance not provided 2018-01-30 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.2125C>G at the cDNA level, p.Leu709Val (L709V) at the protein level, and results in the change of a Leucine to a Valine (CTG>GTG). This variant, previously published as BRCA2 2353C>G, has been observed in at least two individuals with a personal or family history of breast and/or ovarian cancer (Velasco 2005, Infante 2006). BRCA2 Leu709Val was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Leucine and Valine share similar properties, this is considered a conservative amino acid substitution. BRCA2 Leu709Val occurs at a position that is not conserved and is located in the region of interaction with NPM1 (UniProt). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether BRCA2 Leu709Val is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
