GeneDx RCV000657627 SCV000779370 pathogenic not provided 2018-02-01 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.961C>T at the cDNA level and p.Gln321Ter (Q321X) at the protein level. Using alternate nomenclature, this variant would be defined as BRCA2 1189C>T. This substitution creates a nonsense variant, which changes a Glutamine to a premature stop codon (CAA>TAA), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in at least one individual with colon cancer, multiple individuals with breast cancer, and in at least one individual with a personal and family history of breast cancer (Frank 1998, Adem 2003, Spearman 2008, Dworkin 2009, Pearlman 2017, Sun 2017). BRCA2 Gln321Ter is considered pathogenic.
