GeneDx RCV000159851 SCV000209895 uncertain significance not provided 2014-10-03 criteria provided, single submitter clinical testing This variant is denoted BRCA1 c.4305C>G at the cDNA level, p.Asp1435Glu (D1435E) at the protein level, and results in the change of an Aspartic Acid to a Glutamic Acid (GAC>GAG). This variant, also known as 4424C>G using alternate nomenclature, has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA1 Asp1435Glu was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Aspartic Acid and Glutamic Acid share similar properties, this is considered a conservative amino acid substitution. BRCA1 Asp1435Glu occurs at a position that is poorly conserved across species and is located in the SCD domain (Roy 2012). In silico analyses predict that this variant is unlikely to alter protein structure or function; however, splicing models predict that this variant may result in a cryptic splice donor site upstream of the natural splice donor site that may impact splicing. Based on currently available information, it is unclear whether BRCA1 Asp1435Glu is pathogenic or benign. We consider it to be a variant of uncertain significance.
