GeneDx RCV000478267 SCV000568478 pathogenic not provided 2016-05-09 criteria provided, single submitter clinical testing This deletion of 5 nucleotides in BRCA2 is denoted c.6833_6837delTCTTA at the cDNA level and p.Ile2278SerfsX13 (I2278SfsX13) at the protein level. The normal sequence, with the bases that are deleted in braces, is CTTA[TCTTA]GTGG. The deletion causes a frameshift which changes an Isoleucine to a Serine at codon 2278, and creates a premature stop codon at position 13 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. Also published as BRCA2 7057del5 using alternate nomenclature, this variant has been observed in at least one family with multiple breast cancers (Gayther 1997). We consider BRCA2 c.6833_6837delTCTTA to be pathogenic.
