GeneDx RCV000479263 SCV000570694 uncertain significance not provided 2016-06-20 criteria provided, single submitter clinical testing This in-frame duplication of 3 nucleotides in BRCA2 is denoted c.3077_3079dupAGA at the cDNA level and p.Lys1026dup (K1026dup) at the protein level. The normal sequence, with the bases that are duplicated in braces, is AAGA[AGA]GCAA. Using alternate nomenclature, this variant would be defined as BRCA2 3305_3307dupAGA. This duplication of a single Lysine residue occurs at a position that is conserved across species and is located in the BRC1 domain and the RAD51 binding domain (Cole 2011, Roy 2012). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. Since in-frame duplications may or may not inhibit proper protein functioning, the clinical significance of this finding remains unclear at this time and we consider BRCA2 Lys1026dup to be a variant of uncertain significance.
