GeneDx RCV000160127 SCV000210416 uncertain significance not provided 2014-08-19 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.7126G>C at the cDNA level, p.Ala2376Pro (A2376P) at the protein level, and results in the change of an Alanine to a Proline (GCA>CCA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. This variant 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 Alanine and Proline differ in some properties, this is considered a semi-conservative amino acid substitution. BRCA2 Ala2376Pro occurs at a position that is poorly conserved across species, with Proline being the naturally occurring amino acid in several mammals. This variant is within the region of interaction with FANCD2 (UniProt). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available information, it is unclear whether BRCA2 Ala2376Pro is pathogenic or benign. We consider it to be a variant of uncertain significance.
