GeneDx RCV000222425 SCV000279554 pathogenic not provided 2015-11-12 criteria provided, single submitter clinical testing This deletion of 4 nucleotides in BRCA2 is denoted c.5141_5144delATTT at the cDNA level and p.Tyr1714CysfsX10(Y1714CfsX10) at the protein level. The normal sequence, with the bases that are deleted in braces, is AATT[ATTT]GTAT. The deletion causes a frameshift, which changes a Tyrosine to a Cysteine at codon 1714, and creates a premature stop codon at position 10 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.5141_5144delATTT, also published as 5369delATTT and 5369del4, has been observed in multiple individuals with Hereditary Breast and Ovarian Cancer (Beristain 2010, Salgado 2010, Kang 2015). We consider this variant to be pathogenic.
