GeneDx RCV000487131 SCV000564745 likely benign not specified 2014-11-10 criteria provided, single submitter clinical testing This variant is denoted BRCA1 c.4726G>C at the cDNA level, p.Glu1576Gln (E1576Q) at the protein level, and results in the change of a Glutamic acid to a Glutamine (GAA>CAA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA1 Gln1576Q was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Glutamic acid and Glutamine differ in some properties, this is considered a semi-conservative amino acid substitution. BRCA1 Gln1396Arg occurs at a position that is highly variable across species and is not located in a known functional domain. In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on an internal observation of this variant co-occurring with a pathogenic BRCA1 variant, as well as currently available information, we consider BRCA1 Glu1576Gln to be a likely benign variant.
