Description

This deletion of one nucleotide in BRCA2 is denoted c.8940delA at the cDNA level and p.Glu2981LysfsX7 (E2981KfsX7) at the protein level. The normal sequence, with the base that is deleted in braces, is CAAAAAA[A]GAAA. The deletion causes a frameshift which changes a Glutamic Acid to a Lysine at codon 2981, and creates a premature stop codon at position 7 of the new reading frame. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. BRCA2 c.8940delA, also defined as c.8934delA or 9168delA by alternate nomenclature, has been reported in at least one patient with breast cancer (Lin 2016). We consider this variant to be pathogenic.
