GeneDx RCV000478798 SCV000568461 pathogenic not provided 2016-07-18 criteria provided, single submitter clinical testing This deletion of two nucleotides in BRCA2 is denoted c.2798_2799delCA at the cDNA level and p.Thr933ArgfsX2 (T933RfsX2) at the protein level. The normal sequence, with the bases that are deleted in braces, is GACA[CA]GGTG. The deletion causes a frameshift which changes a Threonine to an Arginine at codon 933, and creates a premature stop codon at position 2 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.2798_2799delCA, also published as 3026delCA using alternate nomenclature, has been observed in association with breast and ovarian cancer in patients of Korean descent (Choi 2004, Kim 2012, Kang 2015). We consider this variant to be pathogenic.
