GeneDx RCV000222837 SCV000279471 uncertain significance not provided 2015-10-06 criteria provided, single submitter clinical testing This in-frame deletion of 3 nucleotides in BRCA2 is denoted c.4216_4218delAAA at the cDNA level and p.Lys1406del (K1406del) at the protein level. Using alternate nomenclature, this variant would be described as BRCA2 4444_4446delAAA. The normal sequence, with the bases that are deleted in braces, is AAAT[AAA]GAAC. This deletion of a single Lysine residue occurs at a position that is not conserved and is within the region of interaction with POLH (UniProt). This variant has not, to our knowledge, been published in the literature as being pathogenic or benign. Since in-frame deletions may or may not inhibit proper protein functioning, the clinical significance of this finding remains unclear at this time and we consider BRCA2 Lys1406del to be a variant of uncertain significance.
