GeneDx RCV000215744 SCV000279956 uncertain significance not provided 2016-03-02 criteria provided, single submitter clinical testing This variant is denoted BRCA2 c.109T>G at the cDNA level, p.Ser37Ala (S37A) at the protein level, and results in the change of a Serine to an Alanine (TCA>GCA). Using alternate nomenclature, this variant would be defined as BRCA2 c.337T>G. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. BRCA2 Ser37Ala 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 Serine and Alanine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. BRCA2 Ser37Ala occurs at a position that is not conserved and is located in the PALB2 binding domain (Roy 2012). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether BRCA2 Ser37Ala is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
