GeneDx RCV000480033 SCV000570485 pathogenic not provided 2016-05-31 criteria provided, single submitter clinical testing This deletion of two nucleotides in BRCA1 is denoted c.1323_1324delAT at the cDNA level and p.Ile441MetfsX2 (I441MfsX2) at the protein level. Using alternate nomenclature, this variant would be defined as BRCA1 1442_1443delAT. The normal sequence, with the bases that are deleted in braces, is TAAT[AT]GTAA. The deletion causes a frameshift which changes an Isoleucine to a Methionine at codon 441, and creates a premature stop codon at position 2 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Based on currently available evidence, we consider this variant to be pathogenic.
