GeneDx RCV000657761 SCV000779514 pathogenic not provided 2018-03-23 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.818C>G at the cDNA level and p.Ser273Ter (S273X) at the protein level. The substitution creates a nonsense variant, which changes a Serine to a premature stop codon (TCA>TGA), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. While this specific variant has not been reported in the literature in association with BRCA2-related cancers, a similar variant resulting the same premature stop, BRCA2 c.818C>A (p.Ser273Ter), has been identified in at least one breast and/or ovarian cancer family (Meyer 2003). BRCA2 Ser273Ter is considered pathogenic.
