GeneDx RCV000160101 SCV000210370 uncertain significance not provided 2017-01-26 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.5763T>G at the cDNA level, p.Phe1921Leu (F1921L) at the protein level, and results in the change of a Phenylalanine to a Leucine (TTT>TTG). Using alternate nomenclature, this variant would be defined as BRCA2 5991T>G. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA2 Phe1921Leu 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 Phenylalanine and Leucine share similar properties, this is considered a conservative amino acid substitution. BRCA2 Phe1921Leu occurs at a position that is not conserved and is located in the RAD51 binding domain (Roy 2012). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether BRCA2 Phe1921Leu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
